Abstract
A power harvesting circuit, a rectifier circuit and a capacitor. The rectifier circuit includes a diode circuit and a diode voltage reduction circuit. The diode circuit passes a current when a received RF signal has a first polarity and to substantially blocks the current when the received RF signal has a second polarity. The diode voltage reduction circuit is operably coupled to reduce a voltage drop of the diode circuit. The capacitor is operably coupled to convert the rectified signal into a DC supply voltage.
