This paper presents the three stage CMOS operational amplifier (op amp) with class A output stage designed in SilTerra's 130 nm CMOS technology. The designed three stage op amp employed an indirect feedback compensation technique produces an open loop gain (AOL), for both schematic and layout are 102 dB and 117 dB respectively. the op amp produces 40.5 MHz gain-bandwidth product (GBW), 90 degrees phase margin(PM) and 54.6 V/mu s slew rate (SR) for 5 pF load. Furthermore, the op amp has capability to drive the 15 pF load, produces 25.5 MHz GBW and 45 degrees PM. The circuit was operated at the single supply voltage of 2.5 V with power consumption of 0.977 mW and the layout area was 0.0022 mm(2).
