ABSTRACT:
An electronic device for temperature detection includes a variable threshold voltage that changes in a negative direction in accordance with a temperature change. A reference voltage varies in a positive direction in accordance with the temperature change. A control signal is generated when the reference voltage corresponding to a detection reference temperature and the threshold voltage become equal to each other.
