Abstract
A temperature sensor circuit implemented in electronic circuitry that senses the temperature at a site, digitizes the sensed temperature, and then outputs a signal representing such a sensed temperature. The temperature sensor circuit converts a voltage signal that is proportional to the temperature to a first digital value. The temperature sensor circuit converts a voltage signal that is inversely proportional to the temperature to a second digital value. The sensed temperature is determined as a function of a difference between the first and second digital values.
