摘要：
A low-voltage low-power bandgap voltage reference in 90nm CMOS is designed and simulated. The overall bandgap architecture is optimized to achieve high accuracy temperature and power supply independent voltage reference. It consists of the bandgap core circuit, op-amp, start-up circuit and output stage. The bandgap reference circuit provides reference voltage of 584.7mV +/- 0.8mV with 1.2V +/- 10% power supply and over -40 degrees C to 125 degrees C temperature ranges simultaneously. The total layout area including dummy structures is 100 mu m x 85 mu m.
