High gain and low power design of preamplifier for CMOS comparator

Abstract

In this paper, a low power and low noise preamplifier is designed for Analog to Digital Converter (ADC) operating with 1.2 V power supply. The pre-amplification technique is based on differential pair with cascode stage which provides very low power. The goal of achieving high gain and low power is achieved by operating the circuit in differential mode to… (More)
