Patent ID: 7893681

Claim:
An electronic circuit comprising: a bandgap circuit comprising a first bipolar transistor and a second bipolar transistor wherein the respective bases of the first bipolar transistor and the second bipolar transistor are coupled at a first node; a current mirror circuit comprising a third transistor and a fourth transistor, wherein the respective control terminals of the third transistor and the fourth transistor are coupled at a second node, a fifth transistor, that is a bipolar transistor, coupled to an output terminal of the third transistor wherein a base of the fifth transistor is coupled to a collector of the second transistor, and a sixth transistor, that is a bipolar transistor, coupled to an output terminal of the fourth transistor wherein a base of the sixth transistor is coupled to the first node; a control circuit that controls a current provided to the bandgap circuit based on an output of the current mirror circuit; and a reference voltage output terminal provided between the control circuit and the bandgap circuit and outputting a reference voltage.
