Abstract
A resonant wireless power receiver circuit includes an adjustable impedance matching circuit and a receiver circuit, the impedance matching circuit and the receiver circuit in combination receive a wireless power and generate a resonant output. A rectifier is coupled to the combination of the adjustable impedance matching circuit and the receiver circuit to rectify the resonant output to generate a rectified output. The impedance of the adjustable impedance matching circuit is controlled by a feedback control circuit such that the load impedance of rectified output is regulated at a pre-determined impedance value, or the voltage of the rectified output is regulated at a pre-determined voltage value.
