Design techniques for low-voltage high-speed pseudo-differential CMOS track-and-hold circuit with low hold pedestal

Abstract

A low-voltage pseudo-differential double-sampled track-and-hold circuit with low hold pedestal based on the Miller-effect scheme is proposed. Rail-to-rail operation of bootstrapped switches allows the low-voltage T/H circuit implementation. Simulation results confirm that the proposed circuit is effective in low-voltage applications with low hold pedestal.
