摘要：To augment the temperature dependence of the voltage used to detecttemperature in a semiconductor integrated circuit device having a temperature detection
function, the operating power supply voltage of the semiconductor integrated circuitdevice has needed to be enhanced. It becomes possible for such a semiconductorintegrated circuit device to generate a voltage of great temperature dependence, evenunder a low operating power supply voltage, by including: a temperature-to-currentconverter which outputs a first electric current proportional to temperature; a currentgenerator which outputs a second electric current having extremely small temperaturedependence; a current subtracter which outputs a third electric current proportional to adifferential current obtained by subtracting the second electric current from the firstelectric current; and a current-to-voltage converter which converts the third electriccurrent into a voltage.
