Abstract
A wireless charging receiver as described herein includes a configurable rectifier configured to convert an alternating current input to a direct current output in a single processing stage, wherein the configurable rectifier comprises one or more diodes, and a controller communicatively coupled to the one or more diodes and configured to select one of a plurality of mode cycling schemes and control a present operating mode of the active diodes according to a selected mode cycling scheme. Additionally, an active diode as described herein includes a comparator, a gate driver, a power transistor, and a delay compensation circuit for compensation of at least one of a turn-on delay and a turn-off delay of the active diode, the delay compensation circuit including analog feedback loops.
