ABSTRACT:
A semiconductor temperature sensor comprises independent current sources and bipolar transistors connected to form a Darlington circuit. The bipolar transistors have electrodes each connected to one of the current sources. An output voltage of the semiconductor temperature sensor is adjusted by trimming a current value of at least one of the current sources.
