RFID TAGS WITH POWER RECTIFIERS THAT HAVE BIAS
First Claim
1. A method for generating a rectified signal in a RFID tag, the method comprising:
- receiving an alternating signal;
coupling a first phase of the alternating signal to a gate and to a first non-controlling terminal of a first switching transistor, the first non-controlling terminal of the first switching transistor being one of a source and a drain of the first switching transistor;
applying a first bias voltage between the first non-controlling terminal and the gate of the first switching transistor; and
receiving a rectified voltage between the first non-controlling terminal and a second non-controlling terminal of the first switching transistor.

Abstract
A system and method for generating a rectified signal in a RFID tag. An alternating signal is received by the RFID tag, and a first phase of the alternating signal is coupled to a gate and to a first non-controlling terminal of a first switching transistor. The non-controlling terminal of the first switching transistor is one of a source and a drain of the first switching transistor. A first bias voltage is applied between the first non-controlling terminal and the gate of the first switching transistor and a rectified voltage is received between the first non-controlling terminal and a second non-controlling terminal of the first switching transistor.
