A configurable RFID sensor tag baseband conforming to IEEE 1451.7 Standard

This paper presents a design of sensor tag baseband based on IEEE 1451.7 standard. In this work, general UHF RFID commands is implemented by the hardware state machine in baseband and an embedded 8-bit microcontroller is adopted to process IEEE 1451.7 standard. The simulation and test results show that this design is able to realize the IEEE 1451.7 standard with high flexibility. The power consumption of the baseband is about 18µW at the clock frequency of 1.28MHz and 1.2V power supply, which is suitable for RFID sensor tags and portable application.
