Abstract:
1. An integrated semiconductor circuitry comprising a voltage domain comprising a circuit block of the integrated semiconductor circuitry; a switching unit to connect or disconnect the voltage domain to a supply voltage input comprising a first switch, a second switch, and a third switch, the supply voltage to enable the voltage domain to electrically function; a control signal input to receive a switch control signal; and a signal distribution unit coupled between the control signal input and the switching unit, the signal distribution unit being arranged to output the switch control signal to the first switch delayed by a first time interval and to output the switch control signal to the second switch and to the third switch delayed by a second time interval different from the first time interval, wherein after the first time interval, the switch control signal is to close the first switch, the first switch to thereby output a first current to the voltage domain, and after the second time interval, the switch control signal is to close the second and third switches, the second and third switches to thereby output a second current being greater than the first current.
