Described is a method and apparatus for compensating for a change in an output characteristic of a temperature sensor due to varying temperature. The temperature sensor includes a temperature sensing core, an analog-to-digital converter, a counter, and a temperature compensating circuit. The temperature sensing core generates a sense voltage corresponding to a sensed temperature. The analog-to-digital converter converts the sense voltage into a digital signal and generates a conversion signal. The temperature compensating circuit generates a counter clock signal that varies according to a temperature change. The counter counts the number of pulses of the counter clock signal according to the conversion signal.
