Abstract:
In accordance with a bandgap circuit and a method of starting the bandgap circuit, a start signal is continuously supplied to a differential amplifier circuit to start up the differential amplifier circuit that controls a bandgap core circuit until the differential amplifier circuit has started up, and then the supply of the start signal to the differential amplifier circuit is discontinued after the differential amplifier circuit has started up.
