Abstract :
In this paper an ultra low power UHF RFID tag is introduced. By moving most of system functionality to the RFID reader side, the circuit requirements of the RFID tag circuits are relaxed. Supply voltages for both analog and digital parts are chosen carefully for minimum power consumption. The RFID tag is designed in standard digital 0.13 μm CMOS technology. Simulations results of the main blocks are shown. The power consumption of the chip is only 1 μW, and the chip area is only 0.14 mm x 0.23 mm.
