Patent ID: 8428515

Claim:
A method for generating a rectified output signal in a RFID tag, the method comprising: receiving first and second alternating signals; rectifying a combination of the first and second alternating input signals to generate the rectified output signal, wherein, the rectified output signal is generated from a dual-terminal rectifier device having first and second input terminals, an output terminal, and a gate configured to form a conductive channel to electrically couple the first and second input terminals to the output terminal in response to a gate voltage; rectifying the combination includes applying a first rectified signal to the first input terminal of the dual-terminal rectifier device and applying a second rectified signal to the second input terminal of the dual-terminal rectifier device; and applying the first and second rectified signals comprises rectifying an input signal through a dual-output diode having a first output coupled to the first input of the dual-terminal rectifier device and further having a second output coupled to the second input of the dual-terminal rectifier device.
