A high-order curvature-compensated bandgap voltage reference, which depends on a temperature-dependant resistor radio generated by a high-resistive poly resistor and a diffusion resistor, is presented in this paper. Simulation results with 0.18 μm CMOS process show that the proposed 600 mV voltage reference has a temperature coefficient of 3.7 ppm/°C in the temperature range between -40 and 140°C at 1.6 V supply.
