Claim Text:
1. A system comprising: a functional block; a plurality of power sources, each of the plurality of power sources being maintained at a corresponding voltage; and a switching module having a plurality of switches, the switching module configured to supply power from at least one of the plurality of power sources to the functional block, each of the plurality of switches being controlled by a corresponding switching signal having a voltage value that is one of (i) a ground voltage and (ii) a max voltage, the max voltage corresponding to a highest voltage among the voltages of the plurality of power sources, a first switch of the plurality of switches configured to, during a first period of time, output a first voltage to the functional block, the first voltage being equal to the max voltage, and a second switch of the plurality of switches configured to, during a second period of time, output a second voltage to the functional block, the second voltage being substantially less than the max voltage.
