This paper introduces a high-performance analog front end for a passive UHF RFID transponder IC,which is compatible with the ISO/IEC 18000-6B standard,operating at the 915MHz ISM band with a total supply current consumption less than 8μA.There are no external components,except for the antenna.The passive IC's power supply is taken from the energy of the received RF electromagnetic field with the help of a Schottky diode rectifier.The RFID analog front end includes a local oscillator,clock generator,power on reset circuit,matching network and backscatter,rectifier,regulator,and AM demodulator.The IC,whose reading distance is more than 3m,is fabricated with a Chartered 0.35μm two-poly four-metal CMOS process with Schottky diodes and is EEPROM supported.The core size is 300μm×720μm.
