Abstract
A semiconductor device with temperature compensation functions and a temperature change detecting device which detect temperature changes accurately, without requiring extra mounting space. A sensor unit is composed of first semiconductor components (first-type resistors) having a certain temperature coefficient and second semiconductor components (second-type resistors) having a different temperature coefficient. They are located in the vicinity of a processing circuit that needs temperature compensation. Changes in the temperature of the processing circuit are detected by a temperature change detector which observes a certain property (e.g., resistance) of the first and second semiconductor components constituting the sensor unit. A temperature corrector corrects functions of the processing circuit according to the detection result provided from the temperature change detector.
