Title: A fully differential CMOS operational amplifier implemented with MOS gain boosting technique
Author: Lo, Ping
Abstract: This thesis investigates the gain boosting technique proposed by K .Bult and G . Geelen [9] . An improved cascode circuit that combines both high gain and high speed is developed . Using this cascode circuit , a high performance fully differential operational amplifier is designed . A prototype of the cascode circuit and operational amplifier was fabricated in a 2 |im n -well CMOS technology . Simulation results indicate that the cascode circuit has at least 100 MQ output impedance , while the amplifier has an open loop gain of 98 dB and a unity gain frequency of 17 MHz for 10 pF load capacitor .
