چکیده
In this paper design for 1 volt rail to rail supply voltage output of operational amplifier with common mode feedback amplifier has been presented. The circuit has been simulated using BSIM4 model with 50nm CMOS process. The simulation results show that output voltages for the modified operational amplifier are swinging from 10mV to 990mV i.e. between the rail to rail supply voltages (0 to 1V). Results also show that current drawn by the modified operational amplifier is 310μA in comparison to the circuit for which it is 470 μA and thus shows the reduced power dissipation for the operational amplifier.
