  • Low-Power 12-bit Quasi-Passive Segmented DAC Implemented in 130nm CMOS Technology

    Creator:
    Pierce, Alexander G.
    Abstract:
    This thesis work proposes a low-power 12-bit digital-to-analog converter (DAC) designed in a 130nm process. The DAC to be presented is of a segmented design where the architecture is split into pipelined and thermometer coded segments. This allows for high linearity and low distortion while maintaining high speed and low...

  • Passive source tracking from spatially correlated angle-of-arrival data

    Creator:
    Haisch, Hansjoerg
    Abstract:
    This thesis presents a simulation technique for the post-detection of a point-source trajectory in an isotropic, stationary random medium. The two-dimensional source location is estimated from spatially correlated angle-of-arrival data which are collected simultaneously at two sensor positions. We assume that the data are collected at discrete, constant time intervals...

  • Digital phase-locked loops for multi-GHz clock generation

    Creator:
    Kratyuk, Volodymyr
    Abstract:
    A digital implementation of a PLL has several advantages compared to its analog counterpart. These include easy scalability with process shrink, elimination of the noise susceptible analog control for a voltage controlled oscillator (VCO) and the inherent noise immunity of digital circuits. Several recent digital PLL (DPLL) implementations have achieved...

  • Improved efficiency in medium-power flyback converters

    Creator:
    Ruttanapaibooncharoen, Surin
    Abstract:
    Switch-mode power supplies (SMPS's) not only convert energy, they also consume it. Typical operational efficiencies are approximately 25 to 60% for linear power supplies, and approximately 50-90% for switching power supplies. This means that products whose end-use electronics are dc, such as televisions and DVD players, could consume 50% less...

  • Channel estimation and data detection for mobile MIMO OFDM systems

    Creator:
    Gao, Jie
    Abstract:
    Designing spectral efficient, high-speed wireless links that offer high quality- of-service and range capability has been a critical research and engineering challenge. In this thesis, we mainly address the complexity and performance issues of channel estimation and data detection in multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems over...

  • New configurations for RF/microwave bandstop and lowpass filters

    Creator:
    Peddibhotla, Harish V.
    Abstract:
    This thesis presents new, compact configurations for RF/microwave bandstop and lowpass filters for embedded passive applications. A simple design methodology is presented for designing the folded-transmission line filters on a microstrip platform. Unlike the conventional stub-loaded filter designs, the proposed folded-line filters will have practical dimensions for a wide range...

  • The dynamic simultaneous multithreaded processor

    Creator:
    Ortiz-Arroyo, Daniel
    Abstract:
    This dissertation investigates diverse techniques to support multithreading in modern high performance processors. The mechanisms studied expand the architecture of a high performance superscalar processor to control efficiently the interaction between software-controlled and hardware-controlled multithreading. Additionally, dynamic speculative mechanisms are proposed to exploit thread-level-parallelism (TLP) and instruction-level-parallelism (ILP) on a...

  • Dependency speculation in dynamic simultaneous multi-threading

    Creator:
    Nelson, Jarrod A.
    Abstract:
    The purpose of this thesis is to explore dependency speculation in Dynamic Simultaneous Multi-Threading (DSMT). DSMT is a microprocessor architecture which attempts to extract Thread Level Parallelism (TLP) from single-threaded programs at run-time. This is accomplished by running multiple iterations of program loops in parallel. The DSMT architecture was originally...

  • Energy-Aware Gossip Techniques for Wireless Broadcasting

    Creator:
    Li, Tingzhi
    Abstract:
    The current state of research on gossip techniques for wireless broadcasting is very limited because past research efforts have mostly focused on using gossip techniques for multicast communication. On the other hand, those research efforts that have focused on using gossip techniques for wireless broadcast communications ignore energy efficiency and...

  • Correlated level shifting as a power-saving method to reduce the effects of finite DC gain and signal swing in opamps

    Creator:
    Gregoire, B. Robert
    Abstract:
    This thesis presents methods to reduce the effects of finite opamp DC gain, output voltage swing limitations in opamps, and component mismatches. The primary contribution of this thesis is a new switched-capacitor method named correlated level shifting (CLS). CLS enables true rail-to-rail operation by storing an estimate of the desired...
