description A device for providing a bandgap voltage reference. The device comprises a first switching circuit for providing a first temperature voltage which behaves proportionally to a present temperature, wherein the first switching circuit has two parallel current paths, first and second diode elements being respectively arranged in first and second current paths of the parallel current paths, a second switching circuit for providing a second temperature voltage which behaves in a complementary manner relative to the present temperature, a control circuit which is designed to control a voltage difference between the parallel current paths of the first switching circuit, and a current-bias circuit which is designed to control a ratio of a flow of current through the first diode element to a flow of current through the second diode element, the current-bias circuit comprising a calibration circuit which sets the ratio to a target value.
