Abstract

The present disclosure discloses a bandgap reference power generation circuit and an integrated circuit. The bandgap reference power generation circuit includes a bias circuit and a bandgap reference core circuit. The bias circuit is configured to provide starting current according to a bias voltage. The bandgap reference core circuit is connected to the bias circuit to receive the starting current and goes into a stable operating state according to the starting current to output a preset voltage or preset current. The integrated circuit includes the bandgap reference power generation circuit. By the aforementioned method, the present disclosure can simplify a circuit design and reduce power consumption.
