Abstract
A system and method for achieving self-regulated voltage division among multiple serially stacked voltage planes. The system of the present invention is incorporated within a source voltage plane having a source supply node for supplying current and a source ground node for sinking current supplied therefrom. An intermediate voltage supply node is coupled between the source supply voltage node and the source ground node for dividing the source voltage plane into a plurality of intermediate voltage planes. The self-regulated voltage divider of the present invention includes a first capacitor and a second capacitor that are each controllably coupled between either the source supply voltage node and the intermediate voltage supply node, or between the intermediate voltage supply node and the source ground node, such that a voltage level balance is achieved among the intermediate voltage planes.
