Abstract
The present disclosure provides a power rectifier for a Radio Frequency Identification tag circuit. The power rectifier can be constructed from serially coupled rectifier stages. One of the rectifier stages includes a backflow reduction device or a bias preservation circuit, or both, at least one of which us controlled by a signal derived from a control signal source of the tag circuit.
