ABSTRACT:
An integrated circuit having a temperature sensitive circuit (TSC) to generate a signal indicative of the substrate temperature near the TSC. The integrated circuit has circuitry configured to receive a TSC signal from at least one TSC and to convert the TSC signal to a signal indicative of the integrated circuit's temperature. The thermal control circuit compares the integrated circuit temperature to a threshold and produces a corrective action signal when the temperature exceeds the threshold. The corrective action signal is provided to corrective action circuitry preferably configured to modify the operation of the IC to reduce the IC temperature in proximity to the corresponding TSC.
