Abstract :
This paper proposes a low-power CMOS temperature sensor based on subthreshold MOSFET operation. The circuit was designed on AMIS 0.5 mum technology and ocuppies a silicon area of 0.035 mm2 . Simulations show a responsivity of -8.92 mV/C, a resolution of 0.004degC and power consumption of 10 muW.
