Abstract
An on-chip temperature control system includes a temperature sensor, which monitors a temperature of a chip, and a hysteresis comparator which checks whether the temperature is in an acceptable range. A reference adjustment circuit is responsive to the hysteresis comparator to adjust an on-chip voltage to control the temperature locally by adjusting a local supply voltage, if the temperature is out of range.
