Abstract :
This paper describes a low-power, high-performance RFID tag and wireless power transfer IC for according to the requirements of the EPC Class 1 Generation 2. Operating in the frequency ranges of 860 ~ 960 MHz, the reading operation of tag IC is the -15 dBm minimum power sensitivity. The tag IC consists of an analog part for modulation/demodulation/oscillation, a digital control logic part for controlling the transceiver functionality, and a 512-bit non-volatile memory (NVM) for storing EPC code and a unique identification number. The UHF RFID tag IC is implemented in the 0.18 μm CMOS standard technology. The overall power consumption is only 6 μW at 1.3 V supply voltage. The chip size is 610 μm × 615 μm.
