Abstract:
A bandgap reference circuit includes a first temperature correction circuit that is connected between a power supply terminal and a node between a first resistor and a second resistor. The first temperature correction circuit includes a first transistor that is connected between the first power supply terminal and the node between the first resistor and the second resistor, a control terminal of the first transistor being connected at a junction where the end of a first bipolar transistor connects together with a third resistor, and a fourth resistor that is connected in series between the first transistor and the first power supply terminal.
