Both the main conventional OTA and the boosting amplifiers are fully differential folded cascode.To increase the open-loop gain of the main OTA two auxiliary operational amplifiers(op-amps) are used . These auxiliary op-amps are fully differential folded cascode op-amps with continuous time Common mode feedbacks (CMFB).CMFB is used in auxiliary op-amps to stablise the designed OTA against temperature. This design has been implemented in 0.18µm CMOS Technology using Cadence EDA tool.Spectre simulation shows that the op-amp has DC gain of 171.7958dB , a noise response of 24.1876nV/Hz, power consumption obtained is 295pW and the unity gain bandwidth is more than 1.5GHz.
