Current sensor based closed loop control apparatus

A method and apparatus for performing current control for an integrated circuit are described. In one embodiment the apparatus comprises core logic coupled to receive a first current; a clock generator to generate a first clock signal; and a closed loop current controller coupled to the clock generator and coupled to provide a second clock signal to the core logic based on the first clock signal, the current controller to control an amount of the first current received by the core logic by changing the first clock signal to generate the second clock signal.
