Abstract
A Dual-Path Voltage Multiplier for passive RFID Tags was proposed and fabricated by using a 0.25um CMOS process with additional steps for schottky diodes. The proposed circuit needs only 4 additional diodes, and the area increment compared to conventional one is negligible in multi-stage voltage multipliers. The simulation and measurement results show that the output power capability of proposed multiplier are about two times larger than the conventional half-wave multiplier.
