Abstract: A wireless power enabled apparatus may comprise a wireless power receiver that includes a receive coil configured to generate an AC power signal responsive to a wireless power signal, a rectifier including a plurality of switches configured to receive the AC power signal and generate a DC rectified power signal, a regulator operably coupled with the rectifier to receive the DC rectified power signal and generate an output power signal, and control logic configured to generate a communication signal responsive to adjusting an input impedance of the regulator. A method of operating a wireless power receiver includes generating a rectified voltage responsive to receiving a wireless power signal, generating an output voltage from the rectified voltage with a voltage regulator, and controlling the voltage regulator during a communication mode of wireless power receiver to modulate a characteristic of the voltage regulator with data for transmission to a wireless power transmitter.
