Operational amplifiers are an integral part of many analog and mixed signal systems. As the demand for mixed mode integrated circuits increases, the design of analog circuits such as operational amplifiers in CMOS technology becomes more critical. This paper presents a two stage CMOS operational amplifier, which operates at ±1.8V power supply using TSMC 0.18µm CMOS technology. The OP-AMP designed exhibit unity gain frequency of 12.6 MHz, and Gain of 75.5dB with 100µw power consumption. The gain
