5. CMOS Operational AmplifiersAnalog Design for CMOS VLSI SystemsFranco Maloberti5. CMOS Operational Amplifiers1 Analog Design for CMOS VLSI SystemsFranco MalobertiBasic op-ampThe ideal Operational amplifier is a voltage controlledvoltage source with infinite gain, infinite input impedanceand zero output op-amp is always used in feedback CMOS Operational Amplifiers2 Analog Design for CMOS VLSI SystemsFranco MalobertiTypical feedback configuration V0=V2Z4Z3+Z4Z1+Z2Z1 V1Z2Z1 The error due to the finite gain is proportional to 1 / A0. Thiserror must be smaller than the error due to impedancemismatch.
5. CMOS Operational Amplifiers 21 Analog Design for CMOS VLSI Systems Franco Maloberti Power supply rejection: A signal on the positive bias line determines a modulation in the reference current, which, in turn, gives an equal modulation of the currents in M5 and M6, if the condition of the zero systematic offset is fulfilled.
