چكيده فارسي :
In this paper a low power on-chip temperature sensor, which is appropriate for food monitoring in ultra high frequency radio frequency identification (UHF RFID) passive tag, is proposed. For designing sensor core, MOSFET is used as a temperature sensing element and for decreasing the power consumption, transistors are biased in sub-threshold region. In this sensor for converting the temperature to the digital code, the delay generator and the 9-bit binary counter are utilized. In the design of binary counter, the low power and high speed T flip flap (T-FF) is used in the digital part of sensor, based on gate diffusion input (GDI) technique. The proposed temperature sensor has 38nW power consumption, 0.5V supply voltage and 0.1/0.3 ̊C error due to the Monte Carlo analysis in the temperature range of -10 ̊C to 20 ̊C. The simulation is done with Cadence software in 180nm CMOS TSMC Technology, while the chip area is 0.0125mm2.
