Abstract
Matrix filters useful in low-noise power distribution systems include arrays of capacitors and inductors with interleaved interconnections in an high density interconnect structure so as to achieve nearly ideal performance, i.e., such that capacitor and inductor parasitics are minimized. The matrix filters are bi-directional which help to isolate different load modules by attenuating the switching noise of associated power converters as well as the noise generated by digital loads.
