    Abstract: A power supply circuit can be configured to generate a supply voltage that provides power to the apparatus. A signal generation circuit can be configured to generate a radio frequency (RF) charging signal. An amplification circuit can be configured to amplify the RF charging signal using the supply voltage and to present the amplified charging signal to a power transmitting coil for transmission of wireless power to a remote device. A communication circuit can be configured to detect amplitude variations in the RF charging signal; detect variations in a voltage level of the supply voltage; adjust the detected amplitude variations in the RF charging signal to compensate for detected variations in a voltage level; and decode data represented by the amplitude variations in the RF charging signal based upon the adjusted amplitude variations.

    Abstract: A method for performing foreign object detection in an inductive wireless power transfer system is disclosed. In the embodiment, the method involves obtaining measurements from a base station of a wireless power transfer system during charging and determining transmitter energy loss in a power transmitter, Ptxloss, using the obtained measurements, wherein the transmitter energy loss, Ptxloss, is a function of at least Vcap and PTx, wherein Vcap is proportional to the voltage amplitude across the capacitor of an LC tank circuit in a power transmitter and PTx is the total power supplied to the power transmitter. The method also involves detecting the presence of a foreign object in response to the estimated transmitter energy loss.
