Modeling Research of Rectifier for Passive UHF RFID Tags

摘要：

This paper presents a simple and accurate mathematical model for rectifiers using diodeconnected MOS transistors for passive ultra-highfrequency(UHF) RF identification(RFID) tags. To calculate the efficiency and output voltage we just need a few parameters which make the design of rectifier is greatly simplified. The analysis takes into account the transconductance parameter and body effect, which make the simulation results of the proposed model are very close to those of the actual model based on Hspice simulation even in high rectifier stage situation and the error is less than 10％.
