Abstract:
A rectifier for generating a rectified output and a direct current (dc) power output, the rectifier comprising:(a) an antenna element having first and second terminals, the second terminal connected to ground; (b) a tuning capacitor coupled between the first terminal of the antenna element and ground; (c) 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; (d) a coupling capacitor coupled between the first terminal of the antenna element and the cathode terminal of the first rectifying diode; (e) 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; (f) a storage capacitor coupled between the cathode terminal of the second rectifying diode and ground; and wherein the first rectifying diode, second rectifying diode, and storage capacitor 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.
