Abstract
An apparatus is provided which comprises: a thermal sensor comprising one or more n-type devices or p-type devices that suffer from subthreshold factor variation, wherein the thermal sensor is to generate an output digital code representing a temperature; and a calibration circuitry coupled to the thermal sensor, wherein the calibration circuitry is to trim the effects of subthreshold factor variation from the output digital code.
