集成温度传感器的无源UHF RFID标签设计与验证
Design and Verification of Passive UHF RFID Tag with Integrated Temperature Sensor
摘要
Abstract
A passive RFID tag with an integrated ultra-low-power temperature sensor is designed for the EPC C1 Gen-2 protocol in the UHF frequency band. The sensor tag consists of an analog/RF front-end, a logic control circuit,a temperature sensor circuit,and EEPROM memory in standard CMOS process. Based on the method of digi-talizing and sampling in time-domain, the on-chip temperature sensor is implemented by multiplexing the bias current and clock signal of the analog front-end, and the pulse length associated with temperature is sampled in time-domain and digitalized for thermal sensing. The pre-layout simulation results based on SMIC 0. 18 μm 2P4M CMOS process indicate that the average power dissipation of temperature sensor is only 100 nW,and the sensor tag has a resolution of 0 . 4℃ in the range from-20℃ to 80℃. All the results of either post-simulation or FPGA verifi-cation exhibit that the passive UHF RFID tag has excellent temperature sensor function.关键词
