Abstract :
An op-amp with a push-pull output stage for infrared focal plane array (IRFPA) readout integrated circuit (ROIC) is described in this paper. It works in the class AB mode with little die area. The op-amp is simulated by the SMIC 0.35-μm CMOS process. The circuit is designed to operate from a single 5 V power and drive a capacitive load of 15 pF. The unity gain-bandwidth (GBW) is 30 MHz. the rising slew rate (SR) 34 V/s. and the falling slew rate (SR-) 39 V/s. The common-mode input and the output swing are almost 5 V.
