ABSTRACT:
A temperature sensor circuit comprises a first reference voltage generator configured to generate a first signal that linearly varies with temperature and a first reference voltage signal that maintains a certain level irrespective of temperature, a second reference voltage generator configured to generate a second reference voltage signal by using the first reference voltage signal, and a controller configured to compare the first signal with the second reference voltage signal and control a voltage level of the first signal according to a comparison result.
