  • Design considerations for fast-settling operational amplifiers

    Creator:
    Yang, Howard C.
    Abstract:
    The design considerations for fast-settling operational amplifiers (opamps) differ significantly between sampled-data switchedcapacitor (SC) and conventional continuous-time applications. In SC circuits, the shape of the output voltage waveform of an opamp is of no consequence provided that the output settles to within a specified tolerance of its steady-state value prior...

  • Dynamic and Dual Streaming Methods for H.264 Video and Parallel Performance Modeling

    Creator:
    Johnson, Taylor N.
    Abstract:
    Traditional approaches to streaming H.264 video over a network typically rely on a single method of transport (i.e., reliable or unreliable) and/or use static values for parameters that can have a significant negative impact on the perceptual quality of the received video. This dissertation presents a dynamic method for wireless...

  • Design and computer-aided optimization of RF CMOS power amplifiers

    Creator:
    Gupta, Ravi
    Abstract:
    In recent years, there has been an extensive effort to develop low-cost implementations of radio frequency integrated circuits for consumer applications. This thesis is a research effort in the design and implementation of integrated RF CMOS Power Amplifiers (PAs). A significant challenge in the implementation of RF CMOS ICs is...

  • Liquid crystal thermography : a new system for breast cancer detection

    Creator:
    Bichara, Kamal Fouad
    Abstract:
    A liquid crystal thermographic technique was developed for application to several problems in clinical medicine and physiology. The procedure was inexpensive, rapid, simple, versatile and acceptable to patients. Investigators in the past have used cholesteric liquid crystals for thermography but their use was limited to research in the medical field...

  • Adaptive Streaming Methods using Dual Protocols and Reinforcement Learning

    Creator:
    Gatimu, Kevin
    Abstract:
    The ubiquity of high quality video and proliferation of mobile devices has contributed to an unprecedented rise in video consumption. HTTP, in conjunction with adaptive streaming, has become the de facto mechanism for delivering the vast majority of video as it readily caters to heterogeneous networks and devices. This dissertation...

  • Frequency-domain, parameter estimation for a brushless, doubly-fed machine

    Creator:
    Ramchandran, Ashok
    Abstract:
    A Brushless, Doubly Fed Machine (BDFM) attempts to combine the advantages of conventional induction and synchronous types of electrical machines by its unique architecture. The validation of BDFM designs in an actual test environment requires the estimation of the BDFM model parameters from actual experimentation. Accurate values for the parameters...

  • Compensation techniques for cascaded delta-sigma A/D converters and high-performance switched-capacitor circuits

    Creator:
    Sun, Tao
    Abstract:
    This thesis describes compensation techniques for cascaded delta-sigma A/D converters (ADCs) and high-performance switched-capacitor (SC) circuits. Various correlated-double-sampling (CDS) techniques are presented to reduce the effects of the nonidealities, such as clock feedthrough, charge injection, opamp input-referred noise and offset, and finite opamp gain, in SC circuits. A CDS technique...

  • Design techniques of high-performance switched capacitor circuits in the presence of component imperfections

    Creator:
    Huang, Yunteng
    Abstract:
    This thesis describes design techniques for high-performance switched-capacitor (SC) circuits, primarily for high-linearity low-noise SC circuits in the presence of component imperfections, such as nonlinear op-amp voltage transfer characteristics, capacitor nonlinearities as well as the finite op-amp dc gain and op-amp offset and noise. Various correlated-double-sampling (CDS) schemes are discussed,...

  • A P-well GaAs MESFET technology

    Creator:
    Canfield, Philip C.
    Abstract:
    The semiconductor gallium arsenide (GaAs) has many potential advantages over the more widely used semiconductor silicon (Si). These include higher low field mobility, semi-insulating substrates, a direct band-gap, and greater radiation hardness. All these advantages offer distinct opportunities for implementation of new circuit functions or extension of the operating conditions...

  • Three dimensional electromagnetic FDTD simulation of general lossy structures with nonuniform grid spacing

    Creator:
    Falconer, Maynard C.
    Abstract:
    A new second order accurate nonuniform grid spacing technique which does not depend on supraconvergence is developed for Finite Difference Time Domain (FDTD) simulation of general three dimensional structures. The technique is useful for FDTD simulations of systems which require finer details in small regions of the simulation space by...
