  • Analysis and design of oversampled digital-to-analog converters

    Creator:
    Xu, Xiaofeng
    Abstract:
    Oversampled data converters are becoming increasingly popular for high-precision data conversion. There have been many publications on oversampled analog-to-digital (A/D) converters but relatively few on oversampled digital-to-analog (D/A) converters. In this thesis, issues concerning the analysis and design of the oversampled D/A converters are addressed. Simulation tools and analytical methods...

  • MOSFET-only predictive track and hold circuit

    Creator:
    Qiu, Xiangping
    Abstract:
    High-accuracy and high-speed CMOS track-and-hold (T/H) or sample-and-hold (S/H) circuits are an important part of the analog-to-digital interface. The switched-capacitor (SC) circuits usually contain one or more op-amps whose dc offset, finite gain, finite bandwidth have a big impact on the accuracy of the track-and-hold circuit. Basic correlated double sampling...

  • Oversampling digital-to-analog converters

    Creator:
    Shu, Shaofeng
    Abstract:
    Oversampling and noise-shaping methods for digital-to-analog (D/A) conversion have been widely accepted as methods of choice in high performance data conversion applications. In this thesis, the fundamentals of D/A conversion and oversampling D/A conversion were discussed, along with the detailed analysis and comparison of the reported state-of-the-art oversampling D/A converters....

  • 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,...

  • Improved design techniques for low-voltage low-power switched-capacitor delta-sigma modulators

    Creator:
    Grilo, Jorge
    Abstract:
    This dissertation investigates the constraints which arise when switched-capacitor (SC) delta-sigma modulators are designed for low-voltage operation, targeting also low power dissipation, and proposes methods of improving the performance and optimizing for low power dissipation. This is accomplished by identifying critical elements whose performance can lead to increased power dissipation,...

    Abstract:
    It has been verified by theoretical analysis, circuit simulation and test that two switch transistors in parallel in a simple sample and hold circuit can be achieve high speed with low error voltage due to charge injection. The wide transistor provides low RC time constant when it is closed and...

  • High-linearity switched-capacitor circuits in digital CMOS technologies

    Creator:
    Yoshizawa, Hirokazu
    Abstract:
    In this thesis, novel design techniques have been proposed for implementing high-linearity SC circuits in a standard digital CMOS process. They use nonlinear MOSFET capacitors instead of linear double-poly capacitors. To reduce their nonlinearities, a bias voltage is applied to keep MOSFET capacitors in their accumulation regions. For further reduction...

    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...
