A 3V 10-bit 20MSPS A/D Converter With video clamp

Abstract

This paper describes a 10-bit 20MSPS A/D converter which includes an on-chip video clamp and voltage reference, providing a complete and compact way to digitize video signals. This chip is fabricated in a 0.6pm double-poly CMOS process and dissipates 80mW on a 3V supply.
