Abstract
An integrated circuit includes a digital circuit and an energy management circuit. The digital circuit operates with an internal power supply voltage in synchronism with a clock signal and comprises complementary metal-oxide-semiconductor (CMOS) transistors. The energy management circuit has an input for receiving an external power supply voltage and an output for providing the internal power supply voltage. The energy management circuit is thermally coupled to the digital circuit and sets the internal power supply voltage to a nominal voltage when a temperature of the digital circuit is greater than a boost temperature. The energy management circuit boosts the internal power supply voltage to a boosted voltage greater than the nominal voltage when the temperature of the digital circuit is less than the boost temperature.
