Matrix filters for low-noise power distribution systems

摘要

Matrix filters useful in low-noise power distribution systems include arrays of capacitors (32) and inductors (34) with interleaved interconnections (30,31) in an high density interconnect structure so as to achieve nearly ideal perforrnance, ie, such that capacitor and inductor parasitics are minimized. The matrix filters are bidirectional 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. <IMAGE>
