Abstract

A low voltage high speed class AB op-amp with new structure is presented. The proposed op-amp has been designed to drive a large capacitive load as large as 10pf dedicated for high-resolution high-speed pipelined analog to digital converters. Consuming comparatively low power about 6mw, the proposed class AB op-amps has an output swing of 2.6 Vpp from a single supply of 1.5 volt. It has been observed that this op-amp can be suitable for a 1.5 volt 13-bit Pipelined A/D with sampling rate of 60 MS/S. This op-amp is to be fabricated in standard 0.18u CMOS technology.
