Abstract

This paper is an investigation of off-chip solution of power converters for passive UHF RFID transponders. The power converter, consisting of a chain of schottky diodes and capacitors, is designed and then implemented on Rogers4350 PCB substrate. The ISM unlicensed frequency bands 915 MHz is used for RF signal. The measurement results show that with minimum input power of -4.7 dBm, the power converter achieves 1.8 V/5 muA output driving capability, which is sufficient for the transponder operation. It corresponds to a 3.6 m operating distance when 4-W EIRP radiation is allowed
