A 0.5-V 1-Msample/s 60-dB SNDR Track-and-Hold Circuit

Abstract

A 0.5V 1Msps track-and-hold (T/H) circuit with a 60dB SNDR is presented. The fully-differential circuit is implemented in a 0.25mum CMOS technology, with standard 0.6V VT devices, and uses true low voltage design techniques i.e. with no clock and no voltage boosting
