  • Electrical characterization and circuit modeling of interconnections and packages for high speed circuits by time domain measurements

    Creator:
    Jong, Jyh-ming
    Abstract:
    With edge rates of high speed digital devices pushing into the sub-nano second range, interconnections with the associated packages play a major role in determining the speed, size and performance of digital circuits and systems. The purpose of this study is to develop experimental techniques based on time domain peeling...

  • Automated analysis, design, and optimization of low noise oscillators

    Creator:
    Vytyaz, Igor
    Abstract:
    Low noise oscillators are universally needed in digital systems for clock generation and synchronization, and in radio-frequency communication front-ends for frequency up- and down-conversion. Noise in oscillators results in timing jitter, and limits the clock frequency of digital systems. In radio-frequency communication systems, phase noise in oscillators lowers the signal-to-noise...

  • On output statistics of nonlinear devices : 1) third and higher order information, 2) quadriphase carrier reconstruction, 3) analysis of point processes

    Creator:
    Sherman, Richard Joseph
    Abstract:
    This thesis deals with the output statistics of nonlinear devices. It develops the classical output autocorrelation function in two dimensions and extends the theory to three and four dimensions. Closed form solutions for the output correlation function in two and three dimensions are given for the full- and half-wave rectifier...

  • Liquid-gated carbon nanotube transistor noise sources and sensitivity limits

    Creator:
    Sharf, Tal
    Abstract:
    Low-dimensional electronic materials offer a platform to observe biological processes with unprecedented spatial and temporal resolution. Carbon nanotubes (CNTs) are the closest physical analog to an ideal 1D system and can be scaled and integrated into multiplexed electronic circuitry. The molecular structure of a CNT is also biocompatible, making them...

  • Current mode analog and digital circuit design

    Creator:
    Liang, Guojin
    Abstract:
    In this dissertation, two important current mode circuit design subjects have been explored. In the first part, the switched-current circuit technique has been investigated. The fundamental performance and limitations of this technique are explored. One of the major limitations, the signal distortion caused by clock feedthrough has been substantially reduced...

  • 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...

  • Cellular synthesis of synchronous sequential machines

    Creator:
    Hu, Sung Chiao
    Abstract:
    With the advancing solid-state technology, it is necessary to develop new techniques for synthesizing digital networks. The regular pattern of cellular circuits seems to be the best fitted for the new LSI technology. Recently, cellular implementations of comibinational circuits have received considerable attention but very little attention has been given...

  • Low noise clocking for high speed serial links

    Creator:
    Brownlee, Merrick
    Abstract:
    As the functionality of digital chips continues to increase dramatically, chip- to-chip communication bandwidths must scale accordingly to avoid constraining the overall system performance. Therefore, high speed transceiver design has be- come an important research topic. In particular, the performance of the circuits that are responsible for timing accuracy are...

  • Low-power techniques for supply-noise mitigation in phase-locked loops

    Creator:
    Arakali, Abhijith
    Abstract:
    Modern day digital systems employ frequency synthesizers to provide a common clock to the system. They are undergoing large scale integration due to which, mitigation of the effect of noise on power supply has become a major design consideration in clocking circuits. Rapid scaling of CMOS technology mandates the design...
