In this thesis I explore transistor topologies for high density cell-based arrays that allows for dense computation blocks, small memory cells, and strong signal drivers. This involves simulating different circuit types with HSPICE to determine ideal transistor sizes. Using Magic and the results of the HSPICE simulations, I explore transistor topologies with different ratios of nFets to pFets. An analysis on the technology shows important characteristics for digital systems and how they relate to the explored transistor topologies.; by James Boe-Kian Oey.; Thesis (M.

CMOS (Complementary Metal-Oxide-Silicon) imager technology, as compared with mature CCD (Charge-Coupled Device) imager technology, has the advantages of higher circuit integration, lower power consumption, and potentially lower price. The advantages make this technology competent for the next-generation solid-state imaging applications. However, CMOS processes are originally developed for high-performance digital circuits. Fabricating high-quality embedded image sensors with CMOS technologies is not a straightforward task. This motivates the study of CMOS technologies for imaging applications presented in this thesis. The major content of this study can be partitioned into four parts: (a) A two-stage characterization methodology is developed for sensor optimization, including the characterization of large-area photodiodes and comparative analyses on small-dimension sensor arrays with various pixel structures, junction types of the sensors, and other process-related conditions. (b) The mechanism of hot-carrier induced excess minority carriers occurred at the in-pixel transistors is identified and investigated. The influence of the excess carriers on imager performance is analyzed. Suggestions on the pixel design are provided. (c) Signal cross-talk between adjacent pixels is quantified and studied using a sensor array with a specially designed metal shield pattern...

Semiconductor technologies have been a key to the growth in wireless communication over the past decade, bringing added convenience and accessibility through advantages in cost, size, and power dissipation. A better understanding of how an IC technology affects critical RF signal chain components will greatly aid the design of wireless systems and the development of process technologies for the increasingly complex applications that lie on the horizon. Many of the evolving applications will embody the concept of adaptive performance to extract the maximum capability from the RF link in terms of bandwidth, dynamic range, and power consumption-further engaging the interplay of circuits and devices is this design space and making it even more difficult to discern a clear guide upon which to base technology decisions. Rooted in these observations, this research focuses on two key themes: 1) devising methods of implementing RF circuits which allow the performance to be dynamically tuned to match real-time conditions in a power-efficient manner, and 2) refining approaches for thinking about the optimization of RF circuits at the device level. Working toward a 5.8 GHz receiver consistent with 1 GBit/s operation, signal path topologies and adjustable biasing circuits are developed for low-noise amplifiers (LNAs) and voltage-controlled oscillators (VCOs) to provide a facility by which power can be conserved when the demand for sensitivity is low. As an integral component in this effort...

Over the last decade Organic Light Emitting Device (OLED) technology has matured, progressing to the point where state-of-the-art OLEDs can demonstrate external extraction efficiencies that surpass those of fluorescent lights. Additionally, OLEDs have the benefits over conventional display and lighting technologies of large viewing angles and mechanical flexibility. However, in order to become a commercially viable, widely adopted technology, OLEDs must not only match the long-term stability of competing technologies, but must demonstrate a distinct advantage in efficiency. This thesis presents various strategies for fabricating nanopatterned structures that can be integrated into OLEDs with the aim of improving the external extraction efficiency. Soft nanolithography, colloidal deposition, and preparation of metallic nanoparticle films are among the fabrication techniques investigated for potential applications in enhancing OLED performance.; by John C.

RF systems need high-frequency widely-tunable high-Q bandpass filters for channel selection filters and local oscillators. This thesis describes the design, fabrication and testing of a electromagnetic cavity resonator designed for such applications. Alternative technologies provide wide tuning or high Q, but not both, and are generally not tunable. This resonator is distinguished by its simultaneous high Q near 200 and its wide high-frequency tuning range of 2.5 GHz to 4.0 GHz, which have been experimentally demonstrated. The resonator is fabricated using standard MEMS technologies and consists of a gold-lined capacitor and toroidal inductor cavity formed by etching silicon in potassium hydroxide. Frequency tuning is performed by compressing the cavity to close the capacitor gap. Testing was done with a piezoelectric actuator for this task. The match between the modeled and measured impedance is extremely good up to and beyond 5 GHz, with less than a 1% error in magnitude and phase.; by Stephen Ming-Chang Hou.; Thesis (M.

(cont.) enough to conduct functional genetic surveys.; At present, no widespread tool or technology is available to enable active screening of complex cellular phenotypes. Such desired screens mandate sorting of subsets of cells within an overarching population based upon concerns such as morphological characteristics and/or dynamic processes witnessed in localized regions of individual cells over specified time courses. This thesis presents a sequence of design, simulation, fabrication, and testing routines exercised in demonstrating a first-round, proof-of-concept cytometer offering new avenues for addressing the investigation of such screening processes. The methods and tools outlined in this report employ Microelectromechanical Systems (MEMS) technologies to produce electrode structures sized in accordance with single-cell dimensions that afford viable sorting of individual cells through a novel row/column addressability scheme. This addressing scheme and its associated electrode configurations avoids dependencies upon active on-chip transistor-based devices. Implementing such a "simplified" design reliant upon voltage differences between different sets of activation electrodes framed the problem in the context of an approachable academic research endeavor. This report presents two distinct bioMEMS device implementations incorporating negative and positive dielectrophoretic forces for single-cell capture and manipulation. Offered here is the first-known demonstration of the scalability of dielectrophoretic cell trapping technologies where the interconnect requirements grow proportional to Vn in nxn trapping grids. This reduction in electrical ties to off-chip circuitry renders an operative tool for biological screening assays with the potential for demonstrating sorting operations on populations sizeable; by Brian M.

Interconnect will be a major bottleneck for deep sub-micron technologies in the years to come. This dissertation addresses the communication aspect from a power consumption and transmission speed perspective. A model for the energy consumption associated with data transmission through deep sub-micron technology buses is derived. The capacitive and inductive coupling between the bus lines as well as the distributed nature of the wires is taken into account. The model is used to estimate the power consumption of the bus as a function of the Transition Activity Matrix, a quantity generalizing the transition activity factors of the individual lines. An information theoretic framework has been developed to study the relation between speed (number of operations per time unit) and energy consumption per operation in the case of synchronous digital systems. The theory provides us with the fundamental minimum energy per input information bit that is required to process or communicate information at a certain rate. The minimum energy is a function of the information rate, and it is, in theory, asymptotically achievable using coding. This energy-information theory combined with the bus energy model result in the derivation of the fundamental performance limits of coding for low power in deep sub-micron buses. Although linear...

The design of high gain, wide dynamic range op-amps for switched-capacitor circuits has become increasingly challenging with the migration of designs to scaled CMOS technologies. The reduced power supply voltages and the low intrinsic device gain in scaled technologies offset some of the benefits of the reduced device parasitics. An alternative comparator-based switched-capacitor circuit (CBSC) technique that eliminates the need for high gain op-amps in the signal path is proposed. The CBSC technique applies to switched-capacitor circuits in general and is compatible with most known architectures. A prototype 1.5 b/stage pipeline ADC implemented in a 0.18 [mu]m CMOS process is presented that operates at 7.9 MHz, achieves 8.6 effective bits of accuracy, and consumes 2.5 mW of power. Techniques for the noise analysis of comparator-based systems are presented. Non-stationary noise analysis techniques are applied to circuit analysis problems for white noise sources in a framework consistent with the more familiar wide-sense-stationary techniques. The design of a low-noise threshold detection comparator using a preamplifier is discussed.; (cont.) Assuming the preamplifier output is reset between decisions, it is shown that. for a given noise and speed requirement...

With 3-D integration, the added vertical component could theoretically increase the device density per footprint ratio of a given chip by n-fold, provide a means of heterogeneous integration of devices fabricated from different technologies, and reduce the global RC delay to a non-factor in circuits by using smarter 3-D CAD tools for optimizing device placement. This thesis work will focus primarily on the development and realization of a viable 3-D flow fabricated within MTL. Specifically, the presentation will attempt on answering these questions in regards to 3-D: 1. What enabling technologies were needed for 3-D to work ? 2. Does it really work ? 3. Will the "3-D heat dissipation problem" prevent it from working ? 4. What applications is it good for ? Referring to the first item, a viable 3-D integration flow has been developed on both the wafer-and-die-level, and the enabling technologies were the following: Low temperature Cu-Cu thermocompression bonding, an aluminum-Cu based temporary laminate structure used stabilizing the handle wafer - SOI wafer bond, and tooling optimization of the die-die bonder setup in TRL.; (cont.,) Next, nominal feasibility of the 3-D flow was demonstrated by fabricating a 21-stage and 43-stage CMOS ring oscillators...

The study of proteins in biological systems requires a comprehensive approach: investigating dynamics, interaction and identification. This thesis will examine several technological approaches we have developed to address these needs. To enable the study of the dynamics of biological systems, we have developed a method for using atomic force microscopy (AFM) to image motion on an angstrom scale with microsecond time resolution. As proteins move, diffuse, or are actively trafficked within the cellular environment, they interact with other biological molecules. Protein microarrays offer a high-throughput method of investigating these protein interactions, but their use has largely been hindered by the need to clone and purify thousands of proteins. We have developed a novel technique to pattern proteome-scale microarrays using a cellular lysate, whereby all relevant proteins are synthesized with the correct post-translational modifications. Additionally, we have integrated the identification of proteins with quantitative mass spectrometry (SILAC). Using these arrays we have probed changes in the phosphorylation state of cells in response to activation of the Erb1 and Erb2 receptors. Using our microarray platform we were able to further probe the phosphoproteome for proteins that have multiple post-translational modifications. The widespread use of protein...

In the last few years, AlGaN/GaN high electron mobility transistors (HEMTs) have become the top choice for power amplification at frequencies up to 20 GHz. Great interest currently exists in industry and academia to increase the frequency to mm-wave frequencies. The goal of this thesis has been to identify new solutions to some of the main challenges to increase this frequency performance even further. Electron velocity is a critical parameter affecting the transistor performance. In standard GaN transistors, the extremely high electric fields present in the channel of the device reduce the average electron velocity well below the peak electron velocity, resulting in low cutoff frequencies. In this thesis, we introduced a partial recess in the drain access region of the transistor to engineer the electric field along the channel of the device without introducing parasitic capacitances. By reducing the peak electric field, the average electron velocity is increased by 50%. This new technology has the potential to improve not only the cutoff frequencies, but also the breakdown voltage of GaN transistors. To successfully engineer the electric field in GaN devices, an accurate, reliable and low damage etching technology is needed. However none of the traditional GaN dry etching technologies meets these requirements. This lack of suitable technology has motivated us to develop a new atomic layer etching technique of AlGaN/GaN structures. This technology has been shown to be a self limited process with very high reliability and low damage...

In this thesis, we have used a combination of physical analysis, numerical simulation and experimental work to identify and overcome some of the main challenges in AlGaN/GaN high electron mobility transistors (HEMTs) for high frequency applications. In spite of their excellent material properties, GaN-based HEMTs are still below the theoretical predictions in their high frequency performance. If the frequency performance could be improved, the superior breakdown characteristics of nitride semiconductors would make these devices the best option for power amplifiers at any frequency. To achieve this goal, we have first identified some critical parameters that limit the high frequency performance of AlGaN/GaN HEMTs and then we have demonstrated several new technologies to increase the performance. Some of these technologies include advanced drain delay engineering, charge control in the channel and new N-face GaN HEMTs. Although more work is needed in the future to combine all these new technologies, the initial results are extremely promising.; by Jinwook W.

CMOS technology scaling is creating significant issues for analog circuit design. For example, reduced signal swing and device gain make it increasingly difficult to realize high-speed, high-gain feedback loops traditionally used in switched capacitor circuits. This research involves two complementary methods for addressing scaling issues. First is the development of two blind digital calibration techniques. Decision Boundary Gap Estimation (DBGE) removes static non-linearities and Chopper Offset Estimation (COE) nulls offsets in pipelined ADCs. Second is the development of circuits for a new architecture called zero-crossing based circuits (ZCBC) that is more amenable to scaling trends. To demonstrate these circuits and algorithms, two different ADCs were designed: an 8 bit, 200MS/s in TSMC 180nm technology, and a 12 bit, 50 MS/s in IBM 90nm technology. Together these techniques can be enabling technologies for both pipelined ADCs and general mixed signal design in deep sub-micron technologies.; by Lane Gearle Brooks.; Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2008.; MIT Barker Engineering Library copy: printed in pages.; Also issued printed in pages.; Includes bibliographical references (leaves 179-184).

Continuous scaling of CMOS technology has enabled dramatic performance enhancement of CMOS devices and has provided speed, power, and density improvement in both digital and analog circuits. CMOS millimeter-wave applications operating at more than 50GHz frequencies has become viable in sub-100nm CMOS technologies, providing advantages in cost and high density integration compared to other heterogeneous technologies such as SiGe and III-V compound semiconductors. However, as the operating frequency of CMOS circuits increases, it becomes more difficult to obtain sufficiently wide operating ranges for robust operation in essential analog building blocks such as voltage-controlled oscillators (VCOs) and frequency dividers. The fluctuations of circuit parameters caused by the random and systematic variations in key manufacturing steps become more significant in nano-scale technologies. The process variation of circuit performance is quickly becoming one of the main concerns in high performance analog design. In this thesis, we show design and analysis of a VCO and frequency divider operating beyond 70GHz in a 65nm SOI CMOS technology. The VCO and frequency divider employ design techniques enlarging frequency operating ranges to improve the robustness of circuit operation. Circuit performance is measured from a number of die samples to identify the statistical properties of performance variation. A back-propagation of variation (BPV) scheme based on sensitivity analysis of circuit performance is proposed to extract critical circuit parameter variation using statistical measurement results of the frequency divider. We analyze functional failure caused by performance variability...

The increasing complexity of microsystem design mandates a distributed and collaborative design environment. The high integration levels call for tools and generators that allow exploration of the design space irrespective of the geographical or physical availability of the design tools. The World Wide Web serves as a desirable platform for distributed access to libraries, models and design tools. The rapid growth and acceptance of the World Wide Web has happened over the same time period in which distributed object systems have stabilized and matured. The Web can become an important platform for VLSI CAD, when the distributed object technologies (e.g, CORBA) are combined with the Web technologies (e.g., HTTP, CGI) and Web-aware object oriented languages (e.g., Java). In this thesis, a framework using the Object-Web technologies is presented, which enables distributed Web based CAD. The Object-Web architecture provides an open, interoperable and scalable distributed computing environment for microsystem design, in which Web based design tools can efficiently utilize the capabilities of existing design tools on the Web to build hierarchical Web tools. The framework includes the infrastructure to store and manipulate design objects, protocols for tool communication and WebTop...

Deploying new healthcare technologies for proactive health and elder care will become a major priority over the next decade, as medical care systems worldwide become strained by the aging populations. This thesis presents LiveNet, a distributed mobile system based on low-cost commodity hardware that can be deployed for a variety of healthcare applications. LiveNet embodies a flexible infrastructure platform intended for long-term ambulatory health monitoring with real-time data streaming and context classification capabilities. Using LiveNet, we are able to continuously monitor a wide range of physiological signals together with the user's activity and context, to develop a personalized, data-rich health profile of a user over time. Most clinical sensing technologies that exist have focused on accuracy and reliability, at the expense of cost-effectiveness, burden on the patient, and portability. Future proactive health technologies, on the other hand, must be affordable, unobtrusive, and non-invasive if the general population is going to adopt them.; (cont.)

(cont.) independent receiver coils in parallel or time-axis compression, can be cast as complementary to broadband MRI encoding. This affords broadband non-Fourier MRI with time efficiencies over current fast MRI methods. Finally, we describe the first software and hardware implementation combining these mathematical and physical principles in a proof-of-concept practical broadband MRI system, shown to achieve one order of magnitude increase in efficiency for both 2D and 3D MR imaging.; This dissertation investigates the use of matrix compression techniques to increase the efficiency of data acquisition in Magnetic Resonance Imaging (MRI) scanners, such as those routinely used in hospitals. MRI is based on the Nuclear Magnetic Resonance (NMR) principle which states that nuclei with a non-zero spin may only attain specific quantum spin states when under the influence of a magnetic field. By absorbing a photon of energy equal to the difference between two spin states, nuclei are "excited", flipping spins to a higher energy state. Their classical sum, the magnetization vector, once tipped from the lowest energy state, precesses like a spinning top about the direction of the magnetic field. The frequency of its precession depends entirely upon the field's strength. Therefore...

Personalization capabilities in computer applications attempt to better meet the needs of individuals. The more traditional and widespread paradigm in application design is that the user should adapt to the available application. This requires that the individual user's task be sliced and molded to fit the dimensions offered by an inflexible, monolithic application. It is desirable to have an application that can be shaped to fit each individual user's dynamic needs. However, it is important that this is done in an intuitive and unobtrusive way. In this thesis, we design and evaluate a personalizable application developed to aid life science researchers in their work. We designed the application in Haystack, a platform for developing semantic applications and user interfaces. The application gave the user flexibility in personalizing the way in which information is organized and displayed, while giving users access to the tools necessary to perform their tasks. We selected researchers as the user group to focus on because of the inherent necessity in their work for originality and dynamic adaptation. Life sciences research was chosen as the domain due to its potential to benefit from the application of semantic technologies. We tested how users reacted and adapted to this application by conducting a formal user study.; by Sumudu Weerakoon Watugala.; Thesis (M. Eng.)--Massachusetts Institute of Technology...
