Patent ID: 7109934

Claim:
A rectifier for generating a rectified output and a direct current (dc) power output, the rectifier comprising: an antenna element having first and second terminals, the second terminal connected to ground; a first rectifying diode having a cathode and an anode terminal, the anode terminal connected to ground and the rectified output generated at the cathode terminal; a coupling capacitor coupled between the first terminal of the antenna element and the cathode terminal of the first rectifying diode; a second rectifying diode having a cathode and an anode terminal, the anode terminal coupled to the cathode terminal of the first rectifying diode and the dc current output generated at the cathode terminal; and wherein the first rectifying diode and second rectifying diode are embodied on an integrated circuit having a bonding pad and a chip ground, wherein ground includes the chip ground, and wherein the chip ground includes a back surface of the integrated circuit.
