  • 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...

  • Area efficient D/A converters for accurate DC operation

    Creator:
    Greenley, Brandon Royce
    Abstract:
    The design of mixed-signal integrated circuits has evolved from simple analog and digital circuits operating on the same silicon substrate to the point that now we have complete system on a chip solutions for communication systems. The levels of integration needed to remain cost effective in today's integrated circuit (IC)...

  • A DAC and comparator for a 100MHz decision feedback equalization loop

    Creator:
    Engelbrecht, Linda M.
    Abstract:
    Decision Feedback Equalization (DFE) in a data recovery channel filters the bit decision in the current symbol period in generating the sample at the comparator in the subsequent clock period. The operations of sampling, comparing, filtering the decision bits into a feedback signal, and subtraction of that feedback signal are...

  • Experimental verification of a mismatch-shaping DAC

    Creator:
    Hudson, William Forrest, 1971-
    Abstract:
    Delta-sigma data converters have gained popularity in both analog-to-digital and digital-to-analog converters (ADCs and DACs) due to their simplicity, high linearity and immunity to many analog circuit imperfections. These data converters include features such as oversampling, noise-shaping, and (historically) single-bit quantization. Single-bit converters are preferred for their inherent linearity. This...

  • Resolution enhancement of analog-to-digital converters through computationally simple digital filtering

    Creator:
    Zahl, Eric L.
    Abstract:
    The resolution of analog-to-digital converters can be distinguished as absolute resolution, or average resolution. This study reviews average resolution enhancement techniques and proposes a method which is particularly applicable as a low-cost modification to a high-speed waveform acquisition system. This method uses oversampling combined with computationally simple digital filtering to...

  • Current-mode flash analog-to-digital converter

    Creator:
    Maleki, Mohammad
    Abstract:
    This thesis describes the development of a flash analog-to-digital converter based on current-mode technique. The advantages of current -mode technique are higher speed, smaller chip area, and simple division of reference current based on current mirror. A current-mode comparator is designed consisting of a cascode current mirror and a current...

  • 20-stage pipelined ADC with radix-based calibration

    Creator:
    Yun, Chong Kyu
    Abstract:
    A radix-based calibration technique was previously proposed with a two-stage algorithmic analog-to-digital converter (ADC). The objective of this work is to verify the capability of radix-based calibration for a true multi-stage ADC. In order to prove the idea, a single bit-per-stage, 20-stage pipelined ADC is designed in a 0.35-μm CMOS...
