  • 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...

    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...

  • Low-power high-linearity digital-to-analog converters

    Creator:
    Kuo, Ming-Hung
    Abstract:
    In this thesis work, a design of 14-bit, 20MS/s segmented digital-to-analog converter (DAC) is presented. The segmented DAC uses switched-capacitor configuration to implement 8 (LSB) + 6 (MSB) segmented architecture to achieve high performance for minimum area. The implemented LSB DAC is based on quasi-passive pipelined DAC that has been...

  • A comparative study of lowpass continuous-time delta-sigma modulators with pulse-shaped DACs

    Creator:
    Fang, Jie
    Abstract:
    Recently, continuous-time ΔΣ modulators are appearing increasingly often in both the literature and the marketplace due to their features of inherent antialiasing and relaxed requirements for opamp and so on. However, several nonideal factors such as clock jitter, excess loop delay, inter-symbol interference and so on, degrade the SNR performance...

  • A MOSCAP pipeline pseudo passive DAC

    Creator:
    Behera, Prachee Shree
    Abstract:
    The design of a 10-bit pipelined charge redistribution DAC employing MOSCAPs biased in their accumulation mode is presented in this thesis. A switched capacitor filter and output buffer have also been designed for the system. The effect of MOSCAP nonlinearity on the performance of the pipelined charge redistribution DAC has...

  • Low Frequency Oscillation Reduction Algorithm for Six-step Operation of Three-Phase Inverters

    Creator:
    Ke, Ziwei
    Abstract:
    A power inverter, or inverter, is an electronic device or circuitry that converts direct currents (DC) to alternating currents (AC) in the power electronics family. A three-phase inverter converts DC current to three-phase AC current. Inverters, especially three-phase inverters, have been widely used in many fields including renewable energy applications...
