  • Low voltage techniques for pipelined analog-to-digital converters

    Creator:
    Carnes, Joshua Kenneth
    Abstract:
    To realize pipelined ADCs in deep-submicron processes, low voltage techniques must be developed to work around problems created by limited supply voltages such as the floating switch dead zone, reduced SNR, and reduced OpAmp performance. This thesis analyzes standard and low voltage design issues for pipelined ADCs and proposes a...

  • Ring amplification for switched capacitor circuits

    Creator:
    Hershberg, Benjamin Poris
    Abstract:
    A comprehensive and scalable solution for high-performance switched capacitor amplification is presented. Central to this discussion is the concept of ring amplification. A ring amplifier is a small modular amplifier derived from a ring oscillator that naturally embodies all the essential elements of scalability. It can amplify with accurate rail-to-rail...

  • Design of low OSR, high precision analog-to-digital converters

    Creator:
    Rajaee, Omid
    Abstract:
    Advances in electronic systems have lead to the demand for high resolution, high bandwidth Analog-to-Digital Converters (ADCs). Oversampled ADCs are well- known for high accuracy applications since they benefit from noise shaping and they usually do not need highly accurate components. However, as a consequence of oversampling, they have limited...

  • Architectural compensation techniques for analog inaccuracies in delta-sigma analog-to-digital converters, Architectural compensation techniques for analog inaccuracies in ΔΣanalog-to-digital converters

    Creator:
    Maghari, Nima
    Abstract:
    Delta-sigma analog-to-digital converters (ADCs) are suitable for many applications due to several advantages such as relaxed anti-aliasing filter, high signal-to noise and distortion ratio (SNDR) and most important of all, reduced sensitivity to analog imperfections.This thesis introduces several structures to overcome loop imperfections and stability issues in delta-sigma modulators. First,...

  • Design techniques for PVT tolerant phase-locked loops

    Creator:
    Wu, Ting
    Abstract:
    The continued scaling of deep-submicron CMOS technology enables low-voltage high-frequency phase-locked loops (PLLs) to be fully integrated in complex mixed-signal systems. However, fluctuations due to the manufacturing process and variations in environmental conditions, such as supply voltage and temperature, are also significantly increased. As a result, the performance of PLLs...

  • Time and statistical information utilization in high efficiency sub-micron CMOS successive approximation analog to digital converters

    Creator:
    Guerber, Jon
    Abstract:
    In an industrial and consumer electronic marketplace that is increasingly demanding greater real-world interactivity in portable and distributed devices, analog to digital converter efficiency and performance is being carefully examined. The successive approximation (SAR) analog to digital converter (ADC) architecture has become popular for its high efficiency at mid-speed and...
