摘要： A bandgap reference circuit and method of using the same are provided. The bandgap reference circuit includes a startup component; an output component; and a bandgap core component coupled there-between. The bandgap core component includes a reference point having a voltage associated with an output signal of the output component. A controller is configured for controlling the bandgap core component and the output component to switch between a low power consumption mode and a normal operation mode based on the voltage at the reference point. When the bandgap core component and the output component operate in the normal operation mode, the bandgap reference circuit outputs a stable voltage and has a first power consumption. When the bandgap core component and the output component operate in the low power consumption mode, the bandgap reference circuit has a second power consumption less than the first power consumption.
