Abstract
A power distribution circuit built with wiring layers that reside above an analog circuit is described. The power distribution circuit comprises one or more capacitive structures that reside above the analog circuit. At least one of the one or more capacitive structures has electrodes that provide supply and/or reference voltages and their corresponding currents to said analog circuit. A machine readable medium is described to perform a method in order to design the power distribution circuit. The method includes: assigning a specific supply or reference voltage to each of the electrodes; and, determining wiring dimensions for each of the electrodes. The wiring dimensions for the electrodes of at least one of the capacitive structures is are based at least in part on IR drop concerns.
