摘要/Abstract：
设计了一种符合NCITS 256协议的无源超高频射频识别标签. 标签携带2kbit的标准商用EEPROM. 在读卡器发射功率为915MHz 4W EIRP的情况下，芯片的读距离为1.5m，写距离为0.3m. 芯片在SMIC 0.18μm EEPROM CMOS工艺下流片实现，面积为1mm×1mm. 标签使用Dickson倍压电路从读卡器发射的电磁波中提取能量. Dickson倍压电路使用肖特基管实现，转换效率为25%.
This paper presents a passive UHF radio frequency identification (RFID) transponder with 2 k bit standard commercial EEPROM in compliance with the NCITS 256 protocol. The communication range is 1.5 m for the read operation and 0.3 m for the write operation with 4 W effective isotropic radiated power (EIRP) at 915 MHz. The integrated IC is implemented in SMIC 0.18 μm EEPROM CMOS technology. The die size is 1 mm × 1 mm. The energy of the tag is harvested from RF electromagnetic waves transmitted by the reader with the help of a Schottky diode rectifier and achieves 25% power efficiency.
