Abstract
A rectifier for use in a receiver of a wireless power transfer system for receiving wireless power transferred for a transmitter of the wireless power transfer system. The rectifier comprises a field effect transistor (FET) comprising: a source terminal electrically connected to ground; a drain terminal electrically connected to a receive element of the receiver. The receive element is for extracting power from the transmitter of the wireless power transfer system. The FET further comprises a gate terminal electrically connected to the receive element. The gate terminal is driven by a gate signal in phase with an input signal received at the receive element.
