This paper presents a temperature compensated sub-threshold voltage reference generator which generates a reference voltage of 310 mV at a supply voltage of 0.8 V. Variation of output voltage with temperature over a range of 0 to 100°C is 310.219 to 309.765 mV which gives temperature coefficient of 14.62 ppm/°C. The proposed circuit is designed in 45nm CMOS technology. The quiescent current of the circuit is obtained 17.16and the total power consumption is found to be 13.73.
