Abstract

A bandgap reference circuit is applied to the wide range supply voltage. When a power supply voltage is changed, the change amount of the bandgap voltage generated by the bandgap reference circuit is very low. The bandgap reference circuit includes a mirroring circuit, an input circuit and an operation amplifier. The mirroring circuit generates a first current, a second current and a third current to a first node, a second node and an output voltage of the bandgap reference circuit. The input circuit is connected with the first node to receive the first current and connected with the second node to receive the second current. A positive input terminal of the operation amplifier is connected with the first node. A negative input terminal of the operation amplifier is connected with the second node. An output terminal of the operation amplifier is connected with the mirroring circuit.
