Zusammenfassung:	According to one general aspect, an apparatus may include a first power supply configured to generate a first power signal having one of a plurality of voltages, and a second power supply configured to generate a second power signal that includes a voltage equal to or higher than a voltage of the first power signal. The apparatus may include a first electrical circuit configured to be powered by the first power supply. The apparatus may also include a power mode controller configured to: determine the voltage of the first power signal during the next power state, and generate a selector control signal based upon the voltage of the first power signal. The apparatus may also include a power supply selector configured to dynamically electrically couple a second electrical circuit with either the first power signal or the second power signal, based upon the selector control signal.
