A voltage reference circuit capable of sub-1V operation and with ultra-low power consumption is introduced in this paper. In the proposed circuit, proportional-to-absolute-temperature voltage is generated by using the series-connection of two NMOS devices working in sub-threshold region and the gate-to-source voltage of another NMOS device is adopted to realize the complementary-to-absolute-temperature voltage. Moreover, the temperature compensation is performed by using a switch-capacitor… CONTINUE READING
