This paper presents a low voltage low power RF/analog front-end circuit for passive ultra high frequency (UHF) radio frequency identification (RFID) tag. Temperature compensation is achieved by a reference generator using sub-threshold techniques which requires lower supply voltage than conventional bandgap circuit. Some novel structures are developed to construct the building blocks, including a zero static current power-on reset circuit and a voltage regulator. The RF/analog front-end circuit is implemented with digital base-band and EEPROM in 0.18 μm CMOS EEPROM technology. Measurement results show that the tag has a minimum supply voltage requirement of only 0.75 V.
