摘要：

A low power Bandgap Voltage Reference (BGR) is designed to supply a voltage reference for a low voltage Low-Dropout Regulator (LDO). This bandgap design consists of a bandgap core circuit, an output stage and a start-up circuit. The output of the bandgap adopted sub-1V voltage reference through the output stage circuit. The bandgap is simulated using 0.13 mu m CMOS process. This BGR circuit provides voltage reference of 641mV +/- 1mV over -25 degrees C to 120 degrees C temperature range. The power supply of this BGR circuit is 1.20V and the total current is 20 mu A, thus resulting a low total power consumption of 24 mu W. The total layout area for this bandgap design is 66 mu m x 100 mu m.
