Abstract
A method, apparatus and computer program product are provided to reliably determine a temperature, such as in the time domain. In this regard, an apparatus includes a delay line having a temperature dependent measurement invertor configured to stretch a clock pulse that was generated by an oscillating circuit during circulation of the clock pulse through the delay line. The amount by which the clock pulse is stretched during a cycle about the delay line is dependent upon temperature. The apparatus also includes detection circuitry configured to detect an instance in which clock pulse has been stretched so as to equal or exceed a period of the clock pulse. The apparatus further includes processing circuitry configured to determine the temperature based at least in part upon a number of cycles completed to stretch the clock pulse so as to equal or exceed the period of the clock pulse.
