Design of Low Voltage Low Power CMOS OP-AMPS with Rail-to-Rail Input/Output Swing
Abstract--A novel input and output biasing circuit to extend the input common mode (CM) voltage range and the output swing to rail-to-rail in a low voltage op-amp in standard CMOS technology is presented. The input biasing circuit uses a Switched Capacitor Based Attenuator (SCBA) approach to establish rail-torail common mode input voltage range. And the output biasing circuit uses an Output Driver (OD), with floating bias to give the rail-to-rail swing at output stage. Three different OD schemes in operational amplifier have been proposed and tested the performance with SCBA. The simulation results justify the theoretical analysis.
