Abstract:
In this paper a full wave rectifier is presented for RFID passive tags working at 960MHz frequency. Fordesigning the rectifier multi-stage structure, which has high sensitivity and efficiency, is used for the low amplitudeinput voltage. In order to eliminate the effect of pass transistors threshold voltage, bootstrap circuit which has crosscoupled structure is utilized. For optimizing power conversion efficiency and gaining high output voltage from thelow input voltage the size of the elements and number of stages are modeled and optimized with neural network andTLBO algorithm, respectively. Due to the achieved results from the TLBO algorithm 6 stages are considered for therectifier designing. For the low input voltage 0.6V, the power conversion efficiency and the output DC voltage areachieved 50.8% and 1.52V, respectively. The simulation of the proposed rectifier is done with Cadence software in0.18μm CMOS technology and its layout equals to 0.00525mm2.
