摘要

提出了一种支持EPC第二代协议的全集成无源电池供电半有源超高频RFID应答器芯片。当产生的射频功率足以运行时，所提出的应答器作为无源RFID标签工作，否则它将在使用电池电源的半主动模式下运行。该芯片具有FeRAM和片上温度传感器组成的可重写非易失性存储器。存储器包括用于EPC功能的EPC存储器和用于存储感测数据的温度存储器。半工作状态下的待机电流约为0.5 muA，使用10 mA-hr的薄膜电池，半工作状态下的寿命超过2年。

An EPC Gen 2 compatible passive/semi-active UHF RFID transponder with embedded FeRAM and temperature sensor

A fully integrated passive and battery powered semi-active UHF RFID transponder chip supporting EPC Gen 2 protocol is presented. The proposed transponder works as a passive RFID tag when the generated RF-power is sufficient to operate, otherwise it operates in semi-active mode using battery power. The chip has re-writeable non-volatile memory bank formed by FeRAM and on-chip temperature sensor. The memory consists of EPC memory bank for EPC functionality and temperature bank for storing sensed data. The standby current in semi-active is about 0.5 muA, the lifetime in semi-active mode is in excess of 2 year with a 10 mA-hr thin film battery.
