Abstract
An integrated circuit includes a plurality of thermal sensors integrated within digital domain circuitry and control logic coupled to the plurality of thermal sensors. The control logic retrieves temperature values generated by one or more thermal sensors of the plurality of thermal sensors. The control logic employs the temperature values within a heat-spreading function to determine a time period during which the one or more thermal sensors are to be deactivated and deactivates the one or more thermal sensors for the time period.
