Abstract

An electronic circuit comprises at least one digital logic circuit; and a power control circuit. The power control circuit is operable to adjust the voltage of a power signal supplied to the at least one digital logic circuit in response to a change in a clock frequency provided to the at least one digital logic circuit. In a further embodiment, the power controller is operable to increase the voltage of the power signal applied to the digital logic circuit before a frequency increase is made, and is operable to decrease the voltage of the power signal applied to the digital logic circuit after a frequency decrease is made.
