A 1V 30mW 10b 100MSample/s Pipeline A/D Converter Using Capacitance Coupling Techniques

Abstract

A 10b 100MSample/s pipeline A/D converter in 90nm process consumes 30mW at 1.0V power supply. The proposed capacitance coupling S/H stage and capacitance coupled class-AB amplifier achieve low distortion and low power dissipation at high-speed sampling. The SNDR and SFDR at 100MHz sampling are 54.0 dB and 70.0 dB, respectively
