“…For example, electrocardiography (EKG) pulses sparsely occur and also the workloads do [4]. In a switchedcapacitor circuit, load capacitance varies when connection changes [5,6]. Therefore, OTAs designed for the peak workload without adaptive bias control waste unnecessary power.…”

Abstract-This paper reports an adaptive positive feedback bias control technique for operational transconductance amplifiers to adjust the bias current based on the output current monitored by a current replica circuit. This technique enables operational transconductance amplifiers to quickly adapt their power consumption to various analog workloads when they are configured with negative feedback. To prove the concept, a test voltage follower is fabricated in 0.5-μm CMOS technology. Measurement result shows that the power consumption of the test voltage follower is approximately linearly proportional to the load capacitance, the signal frequency, and the signal amplitude for sinusoidal inputs as well as square pulses.
