N2 - In this study, the prototype of CMOS Inverter-Based Differential Amplifier has been developed with ROHM 0.18μm standard CMOS process. In order to get high DC gain, Nauta's operational transconductance amplifier (OTA) is adopted as the amplifier stage and nested miller compensation is selected as the phase compensation. The measurement results indicate that power consumption is 18 μW, DC Gain is 71 dB, input offset voltage is 1.2 mV, CMRR is 57 dB and PSRR is 83 dB at the supply voltage VDD =1 V.
