Abstract:
1. A method of configuring on-chip supply voltage being supplied to one or more chip circuits, said method comprising: selecting a first voltage supply mode; floating one side of a first capacitor in a pair of series connected capacitors, the other side of said first capacitor being connected to a first side of a second capacitor of the series connected pair; alternately switching opposite sides of said second capacitor to a voltage supply output (V selecting a second voltage supply mode; alternately floating and coupling said one side of said first capacitor to said first supply voltage and simultaneously switching the other side of said second capacitor to said voltage supply output when said one side is floating, said first side of said second capacitor being alternately switched in and out to said voltage supply output, the other side of said second capacitor being alternately switched between said second supply voltage and said voltage supply output, said voltage supply output supplying a second output voltage; and waiting to reselect said first voltage supply mode.
