ABSTRACT:
A bandgap reference circuit, taking two or more power supplies as the input power supply for outputting a reference voltage, includes a first reference circuit, a second reference circuit, a power selection circuit and a switch circuit. The first and second reference circuits receive two respective power supplies for producing first and second voltages, respectively. As the power selection circuit takes the first power voltage level as the input voltage, the power selection circuit outputs a first control signal; while the power selection circuit takes the second power voltage level as the input voltage, the power selection circuit outputs a second control signal. The switch circuit is coupled to the power selection circuit, the first reference circuit and the second reference circuit. As the switch circuit receives the first control signal, it outputs the first voltage; while the switch circuit receives the second control signal, it outputs the second voltage.
