Abstract
A temperature sensor circuit which includes: an adjustment circuit which generates a first divided voltage obtained by dividing a reference voltage; a current generation circuit which has a transistor element and generates a current corresponding to a gate voltage of the transistor element, the first divided voltage being supplied to a gate terminal of the transistor element; a voltage generation circuit which includes a diode element to which the current is supplied, an analog voltage being generated between both ends of the diode element; and an analog/digital (A/D) conversion circuit which compares a second divided voltage obtained by dividing the reference voltage with the analog voltage and converts the analog voltage into a digital value.
