ABSTRACT:
An on-chip thermal sensing circuit is disclosed. The thermal sensing circuit including a detection circuit located on an integrated circuit (IC) for detecting a local temperature of the IC. The output of the thermal sensor has a frequency that is directly related to the local temperature. The detection circuit has an associated time constant that is used to produce the frequency.
