A Brief History of Nyquist Analog-to-Digital Converters

Abstract

This paper reviews and discusses a brief history of Nyquist ADCs. Bipolar flash ADCs for early development stage of HDTV and digital oscilloscopes, a Bi-CMOS two-step flash ADC using resistive interpolation for home HDTV receivers, a CMOS two-step flash ADC using capacitive interpolation for handy camcorders, pipelined ADCs using CMOS operational amplifiers, CMOS flash ADCs using dynamic comparator and digital offset compensation, SAR ADCs using low noise dynamic comparators and MOM capacitors, and hybrid ADCs are reviewed.
