Abstract
A temperature control apparatus is disclosed. An integrated circuit (IC) includes a plurality of temperature sensors, a first thermal control loop, and a second thermal control loop. The first thermal control loop is configured to control temperature of the IC by reducing a frequency of a clock signal provided to the IC in response to a temperature at one of the plurality of temperature sensors reaching a first temperature threshold. The second thermal control loop is configured to control temperature of the IC by dithering the clock signal provided to the IC in response to a temperature at one of the plurality of temperature sensors reaching a second temperature threshold that is greater than the first temperature threshold.
