ABSTRACT:
A temperature sensing circuit comprises a temperature sensing unit for generating a reference voltage having a constant level, regardless of a temperature fluctuation, and a variable voltage to be changed according to the temperature fluctuation, and a comparison unit for comparing the reference voltage to the variable voltage, detecting an ambient temperature and generating a temperature detecting signal.
