This paper presents a novel low power, low voltage CMOS bandgap reference (BGR) that overcomes the problems with the existing BJT-based reference circuits by using a MOS transistor operating in sub-threshold region. A proportional to absolute temperature (PTAT) voltage is generated by exploiting the self-bias cascode branch, while a Complementary to Absolute Temperature (CTAT) voltage is generated by using the threshold voltage of the transistor. The proposed circuit is implemented in 65[Formula: see text]nm CMOS technology. Post-layout simulation results show that the proposed circuit works with a supply voltage of 0.55[Formula: see text]V, and generates a 286[Formula: see text]mV reference voltage with a temperature coefficient of 59[Formula: see text]ppm/∘C. The circuit takes 413[Formula: see text]nA current from 0.55[Formula: see text]V supply and occupies 0.00986[Formula: see text]mm2 of active area.
