Abstract: An integrated circuit may include multiple power consuming cores, multiple sets of power gates, and a control circuit. Each set of power gates can be configured to provide one or more power paths to provide power to a corresponding power consuming core. The control circuit can be configured to switch the set of power gates allocated to a power consuming core in a sequence of switching events during an activation period in response to one of the power consuming cores being turned on or off. The sequence of switching events may vary the number of power gates being switched or vary a time interval between the switching events.

Abstract: A system includes a first set of conductors coupled to at least one power source; a second set of conductors coupled to a first power consuming portion of an integrated circuit; multiple power gates coupled between the first and second sets of conductors; and a control circuit configured to gradually activate the multiple power gates during an activation period to provide a nonlinear rate of change of an impedance between the first and the second sets of conductors during the activation period.
