Abstract:
1. A circuit arrangement comprising: an electronic component coupled to at least one common power supply node and configured to provide a first signal having a variation in time that is based on power supply via the at least one common power supply node; a detecting circuit coupled to the electronic component, the detecting circuit being configured to detect the first signal and to provide a digital switch array control signal based on the variation in time of the first signal; a switch array coupled between the at least one common power supply node and at least one power supply source; at least one additional electronic component coupled to the at least one common power supply node and configured to provide at least one additional signal, wherein variation in time of the at least one additional signal is dependent on power supply via the at least one common power supply node, and wherein the at least one additional signal is time-shifted with respect to the first signal; at least one additional detecting circuit coupled to the at least one additional electronic component, the at least one additional detecting circuit being configured to detect the at least one additional signal and to provide at least one additional digital switch array control signal based on the variation in time of the at least one additional signal; wherein the switch array comprises at least one first switch and at least one additional switch coupled between the at least one common power supply node and the at least one power supply source; wherein the switch array is configured to control the power supply via the at least one common power supply node based on the digital switch array control signal and the at least one additional digital switch array control signal; wherein the at least one first switch is controlled by the digital switch array control signal and the at least one additional switch is controlled by the at least one additional digital switch array control signal.
