度測定装置。[Claims for Utility Model Registration] An amplifier circuit using a field effect transistor (FET), which supplies a reverse bias voltage between a parasitic diode connected between the source and drain of the FET and the source and drain of the FET. It is characterized by comprising a constant voltage source and a switch that turns on and off the reverse bias voltage, and measures the forward voltage drop of the parasitic diode by turning on the switch for a predetermined period while the gate input is off. temperature measuring device.
