Abstract:A novel high precision high order curvature-compensated bandgap reference (BGR) is presented in this paper designed using the subthreshold current of self-cascode transistors in standard digital 0.18 μm CMOS process. Simultaneously its temperature coefficient is typically 4.6 ppm/ • C in the temperature range of −25 to 120 • C with a supply current of 17.25 μA. A power supply rejection ratio (PSRR) of −51 dB is achieved while the layout area is no more than 0.0022 mm 2 .
