Abstract
A wireless power transfer (WPT) receiver circuit includes a receive coil to couple to a transmit coil of a WPT transmitter circuit. A rectifier is coupled to the receive coil to generate a rectified voltage. The rectifier comprises a bridge rectifier circuit including a first set of switching elements. A load modulation circuit facilitates communication between the WPT receiver circuit and the WPT transmitter circuit. The load modulation circuit includes a single modulation capacitor and one or more modulation switching elements. At least one node of one of the modulation switching elements is connected to an input node of the rectifier.
