Abstract:
1. A semiconductor device, comprising: a temperature detection element, a voltage to be applied to the temperature detection element so as to allow a current greater than or equal to a prescribed value to flow through the temperature detection element changing in accordance with an ambient temperature; a constant current source for applying a voltage to said temperature detection element so as to allow a reference current greater than or equal to said prescribed value to flow through said temperature detection element, a first leakage current correction circuit for allowing a current having approximately the same magnitude and the same direction as a magnitude and a direction of a current flowing between said first power source node and said second power source node via said first potential-fixing node and said second resistor node, to flow between said first power source node and said second power source node, not via said first diffused resistor but via said reference current transistor.
