Abstract
An embodiment of a temperature sensor providing a digital signal representative of temperature comprises a measurement unit providing a first measurement current equal to the sum of at least a first current proportional to temperature and of a second current; a comparator capable of providing a comparison signal which depends on the comparison between the first current and the difference between a third current and the second current; a coding unit receiving the comparison signal and providing said digital signal; a digital-to-analog converter capable of providing the second current and the third current, said difference corresponding to the conversion of said digital signal; and a unit for providing a reference voltage.
