ABSTRACT:
Power control circuitry for controlling connection of a voltage source to a switched power rail powering an associated circuit is provided. A plurality of switch blocks are connected in parallel between the switched power rail and the voltage source, each switch block being controlled by an enable signal provided by a switch controller. The switch controller performs a turn-on sequence providing a series of enable signal patterns to the switch blocks. The switch controller applies a time varying generation operation to at least one sequence stage of a predetermined turn-on sequence to produce a corresponding enable signal pattern for that sequence stage. When the turn-on sequence is later repeated, the enable signal pattern produced for at least one of the sequence stages differs from the enable signal pattern previously produced for that sequence stage.
