Abstract
A thermal management system is described which may be implemented on a semiconductor die. The system may include a thermal sensor thermally coupled to the die to sense the temperature of the die and generate an output representing the sensed temperature, and an adjustable compensation circuit coupled to the thermal sensor to compensate the thermal sensor output. The adjustable compensation circuit may be applied to the thermal sensor or to a threshold.
