Power Noise Suppression Using Power-and-Ground via Pairs for Signal and Power Integrity

In this paper, a simultaneous switching noise suppression method combining Electromagnetic Bandgap (EBG) and power-and-ground via pairs is proposed. This structure is partially etched only in the noise source and sensitive circuit parts on the plane, without using a bridge structure. In terms of multiple layers, it is connected through a thin dielectric and via arrays. Compared to the traditional EBG structure, this structure ensures excellent noise suppression capability while maintaining pretty signal integrity and power integrity. Simulation results demonstrate that this structure possesses better signal integrity and power integrity with a steep suppression level of −40dB from 1.61 to 15GHz
