Abstract
The temperature sensor circuit includes a diode that is connected to a first potential at a cathode thereof. The temperature sensor circuit includes a voltage dividing circuit that is connected to an anode of the diode at a second end thereof and outputs a divided voltage. The temperature sensor circuit includes a second amplifying circuit that receives the first signal at a first input end thereof, receives the divided voltage at a second input end thereof, is connected to a first end of the voltage dividing circuit at an output end thereof and outputs a second signal so as to make the divided voltage equal to the first signal. The temperature sensor circuit includes a measuring circuit that calculates a voltage difference between the first signal and the second signal and outputs an output signal based on the result of the calculation.
