Simultaneous switching noise (SSN) is a signiflcant problem in high-speed circuits. To minimize its efiect and improve the electrical characteristics of circuits such as signal integrity (SI) and power integrity (PI), a novel power plane with planar electromagnetic bandgap (EBG) structure is proposed for SSN suppression in printed circuit boards (PCB) in this paper. In which a kind of improved long bridge is used and the equivalent parallel inductance can be increased signiflcantly. Compared to the typical spiral bridge EBG structure with the same parameters, the long bridge EBG structure will change bandgap into dual-band, with lower center frequency and wider bandwith. The efiectiveness and accuracy of this structure are verifled by both simulations and measurements. |
