In this paper, a CMOS bridge rectifier for HF and microwave RFID systems is presented. The proposed RFID CMOS bridge rectifier is composed with two NMOSs and two PMOSs whose gates are all commonly connected to the antenna. The simulation results obtained with SPICE show the well rectified and high enough DC output voltages for frequencies of 13.56㎒, 915㎒, and 2.45㎓ which are used in various RFID systems. The obtained DC output voltages are sufficient for driving the microchip in RFID Transponders.
