Abstract
Many embodiments provide an implant power management unit (IPMU) that includes a reconfigurable active rectifier (AR) for wireless power transfer (WPT), where the AR is configurable to operate in a plurality of different modes of operation, an adaptive load control (ALC) unit that accommodates power delivery with load requirements, where the ALC unit is configured to control AR voltage based upon a desired value, control circuitry that is configured to enable a full bridge rectifier in a regular mode of operation of the AR, a feedback circuit that adaptively generates offset current to compensate for switch delays in at least one active NMOS diode, and a feedback circuit that adaptively generates offset current to compensate switch delays in at least one active PMOS diode.
