This paper describes the Gain boost class–C inverter circuit, which is used in place of OTA (Operational Transconductance Amplifier) block in ΣΔ modulator .The gain boost class-C inverter behaves as a low voltage, subthreshold amplifier and boosts its DC gain for the high precision requirement. First a traditional cascade class-C inverter is presented, another inverter circuit present in this paper is “Gain boost class-C inverter”. It is implemented in 50nm CMOS technology and simulation is done using the LTSpice simulation tool.
