A Hybrid Electromagnetic Bandgap (EBG) Power Plane with Discrete Inductors for Broadband Noise Suppression

A new type of hybrid electromagnetic bandgap (EBG) structure is proposed for noise suppression in a power distribution network (PDN) where each unit cell contains the combined features of series surface mounted technology (SMT) inductors and at least one SMT decoupling capacitor as a shunt load. An example is shown where effective noise suppression is demonstrated to cover a frequency range of near 25 MHz to at least 10 GHz.
