Abstract
A CMOS temperature sensor includes a first circuit portion for generating a voltage signal whose value increases with the temperature to be sensed, and a second circuit portion for generating an electric voltage signal whose value decreases with the temperature to be sensed. A comparator is provided as an output stage for comparing the values of both voltage signals. The generator element of the second circuit portion is a vertical bipolar transistor connected in a diode configuration.
