Claim:
1. A method, comprising: receiving two or more current measurement signals associated with two or more supply rails, wherein each current measurement signal is associated with one supply rail from the two or more supply rails; computing a difference signal for each supply rail as a difference between the current measurement signal and an average signal value of the two or more current measurement signals; selecting a first supply rail of the two or more supply rails, the first supply rail having a maximum value of the difference signals; enabling the first supply rail to source current into a merged supply rail; after enabling the first supply rail, determining a second supply rail of the two or more supply rails has the maximum value of the difference signals; disabling the first supply rail to source current into the merged supply rail; and enabling the second supply rail to source current into the merged supply rail.
