Radio frequency identification (RFID) sensor tag provides several advantages including battery-less operation and low cost, which are suitable for long-term monitoring. This paper presents a self-powered RFID temperature sensor tag for online temperature monitoring in substation. The proposed sensor tag is used to measure and process the temperature of high voltage equipments in substation, and then wireless deliver the data. The proposed temperature sensor employs a novel phased-locked loop (PLL)-based architecture and can convert the temperature sensor in frequency domain without a reference clock, which can significantly improve the temperature accuracy. A twostage rectifier adopts a series of auxiliary floating rectifier to boost its gate voltage for higher power conversion efficiency. The sensor tag chip was fabricated in TSMC 0.18㎛ 1P6M CMOS process. The measurement results show that the proposed temperature sensor tag achieve a resolution of 0.15 ℃ /LSB and a temperature error of -0.6/0.7 ℃ within the range from -30 ℃ to 70 ℃. The proposed sensor tag achieves maximum communication distance of 11.8 m.
