A 40.68-MHz Active Rectifier With Hybrid Adaptive On/Off Delay-Compensation Scheme for Biomedical Implantable Devices

This paper presents an active rectifier operating at 40.68 MHz for wirelessly powered biomedical implant devices. The commonly used current-injection-based compensation and delay-based compensation schemes are analyzed. To tackle design difficulties at high frequency, a hybrid delay-compensation sch...
