Abstract
Aspects of the disclosure provide methods and systems to design a distributed discrete capacitor bank incorporating power plane capacitance to concentrate the suppression of AC coupling to the frequencies caused by clocks and signal transitions. Aspects of the disclosure provide a procedure for designing a distributed capacitor bank from a combination of bulk capacitors, ceramic capacitors and/or plane capacitance that provides the desired impedance Z to suppress noise at all desired frequencies.
