Abstract
An integrated circuit includes a bandgap reference generator and a voltage regulator. The bandgap reference generator includes a first current path, and a first bipolar transistor with an emitter-collector path in the first current path. The voltage regulator includes a second current path, wherein the second current path mirrors the first current path; a resistor configured to receive a current of the second current path; a second bipolar transistor with a base and a collector of the second bipolar transistor being interconnected; and a third bipolar transistor connected in series with the second bipolar transistor and the resistor. A base and a collector of the third bipolar transistor are interconnected.
