  • Efficient use of time information in analog-to-digital converters

    Creator:
    Hu, Yue
    Abstract:
    Time-domain data conversion has recently drawn increased research attention for its highly digital nature in favor of process technology scaling. Also, as the time information being carried by binary voltage, time-domain operation is much less sensitive to voltage noise compared to conventional voltage domain operation. However, for analog-to-digital converter (ADC)...

  • Delta-sigma modulators employing continuous-time circuits and mismatch-shaped DACs

    Creator:
    Zhang, Bo
    Abstract:
    Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital and digital-to-analog converters. These oversampled data converters have several advantages over conventional Nyquist-rate converters, including an insensitivity to many analog component imperfections, a simpler antialiasing filter and reduced accuracy requirements in the sample and hold. Though the initial...
