摘要

本文研究了无源超高频RFID应答器功率转换器的片外解决方案。该功率转换器由一系列肖特基二极管和电容组成，设计并在罗杰斯4350 PCB基板上实现。射频信号使用ISM免授权频段915mhz。去嵌入测量结果表明，在最小输入功率为-4.7dBm的情况下，功率变换器的输出驱动能力为1.8V/5muA，足以满足应答器的工作要求。在允许4w EIRP辐射的情况下，对应3.6m的工作距离

Design and implementation of a high efficient power converter for self-powered UHF RFID applications

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 de-embedded measurement results show that with minimum input power of -4.7dBm, the power converter achieves 1.8V/5muA output driving capability, which is sufficient for the transponder operation. It corresponds to a 3.6m operating distance when 4-W EIRP radiation is allowed
