Abstract :
In this paper, a new temperature sensor based on the performance of carbon nanotube transistors in the subthreshold region is designed and simulated which leads to reduction of power consumption. Also, a differential amplifier is used in the output of the sensor. in order to keep the values of gain and common mode level voltage due to temperature changes, a method has been proposed that can compensate for these parameters variation due to temperature variation in the range of -30 ºC to +125 ºC. The proposed temperature sensor with its amplifier can be used as a system on the chip surface for temperature monitoring and control. The proposed temperature sensor in the CNTFET carbon nanotube field effect transistor technology with a supply voltage of 0.5 V in the sub-threshold area is simulated by HSPICE software with a 32nm CNT model. The simulation results show that at proposed circuits can measure the temperature in range of -30 ºC to +125 ºC linearly with a sensitivity of 1 mV/ ºC and consumes only 123 nW at room temperature. Also, the error measured at 125 ºC is about 2.5 mV, which means an error of 1.25 ºC at this temperature.
