Abstract
A composite rectifying charge storage device, consisting of a rectifier and capacitor which share common elements, is combined in a circuit with an antenna for remote energization in response to an external electromagnetic or electrostatic AC field. The energized composite device extracts power (voltage or current) and may be implemented in a variety of circuit configurations, such as a power supply for driving circuit components, e.g., radio frequency identification (RFID) circuitry, or for use in parameter sensing applications which may include a light emitting component, and others.
