A full wave voltage multiplier for passive RFID transponders is presented. The current driving capability of the proposed rectifier is remarkably improved at the cost of only a small increase in layout area compared to the widely used conventional half wave voltage multiplier. The communication distance of RFID systems can be extended due to the improved RF carrier to DC power conversion capability of the proposed voltage multiplier.
