Abstract :
In this paper, we present a CMOS operational amplifier with high DC-gain and high output swing despite a low supply voltage. This Op Amp uses a new technique called the TransComposit. The Op Amp has been manufactured in standard 0.5-¿m CMOS technology. Using this technique the Op Amp can operate at a 3V supply voltage at a 67db DC-gain and 116MHz unity gain frequency with 25-pF load capacitance.
