摘      要：This paper presents a fully integrated passive UHF RFID tag chip complying with the ISO18000-6B *** tag chip includes an RF/analog front-end,a baseband processor,and a 512-bit EEPROM *** improve power conversion efficiency,a Schottky barrier diode based rectifier is adopted.A novel voltage reference using the peaking current source is discussed in detail,which can meet the low-power,low-voltage requirement while retaining circuit *** of the analog blocks are designed to work under sub-1 V to reduce power consumption,and several practical methods are used to further reduce the power consumption of the baseband *** whole tag chip is implemented in a TSMC 0.18μm CMOS process with a die size of 800×800μm;. Measurement results show that the total power consumption of the tag chip is only 7.4μW with a sensitivity of -12 dBm.
