Abstract
A bandgap reference circuit includes a feedback transistor, a reference setting circuit, an amplification circuit and an output transistor. A source of the feedback transistor is configured to connect to a first power supply, and a drain of the feedback transistor is configured to connect to a first node. The reference setting circuit includes a first bridge arm and a second bridge arm which are connected in parallel. An inverting input terminal of the amplification circuit is connected to the first bridge arm, and a non-inverting input terminal of the amplification circuit is connected to the second bridge arm. A gate of the output transistor is connected to an output terminal of the amplification circuit, and a source of the output transistor is connected to the first power supply.
