ABSTRACT:
A sampled-data, current-mode circuit implements analog functions in a standard digital process. Among sampled-data current-mode circuits, the current S/H (CSH) circuit is a key component. This fully differential CSH circuit was implemented in a 1.2 .mu.m N-well double-poly double metal CMOS technology adapted to 8-bit resolution at a 15 MHz sampling rate.
