A Passive NCITS 256 UHF RFID Transponder

Abstract
This paper presents a passive UHF radio frequency identification (RFID) transponder with 2k bit standard commercial EEPROM in compliance with the NCITS 256 protocol.The communication range is 15m for the read operation and 0.3m for the write operation with 4W effective isotropic radiated power (EIRP) at 915MHz.The integrated IC is implemented in SMIC 0.18μm EEPROM CMOS technology.The die size is 1mm×1mm.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.-
