Power-adaptive operational amplifier with positive-feedback self biasing

Abstract—This paper introduces a positive-feedback selfbiasing technique for operational amplifiers (op-amps) which enables their power consumption to adapt to their environment: The power consumption of one our op-amps scales almost linearly with load capacitance, input signal frequency, and output signal swing. A voltage follower built in the MOSIS/AMI 0.5µm process with our op-amp has a
