THREE-STAGE FREQUENCY-COMPENSATED OPERATIONAL AMPLIFIER FOR DRIVING LARGE CAPACITIVE LOADS

摘要

A three-stage frequency-compensated operational amplifier includes a first-stage circuit, a second-stage circuit incorporated with a first compensation circuit, a third-stage circuit, and a second compensation circuit. The three-stage frequency-compensated operational amplifier functions as a two-stage operational amplifier at high frequencies, thereby capable of driving large capacitive loads with low power consumption.
