A New Uniplanar Electromagnetic Bandgap Power Plane With Broadband Suppression of Simultaneously Switching Noise

Abstract

Abstract-A new uniplanar electromagnetic bandgap (EBG) power/ground planes is proposed with broadband suppression of simultaneously switching noise (SSN) from 370 MHz to 4.9 GHz. Meander line bridge is used to increase the inductance between the two neighboring units, which can make the proposed power/ground structure suppress the SSN at low frequencies effectively. Excellent SSN suppression performance is validated both numerically and experimentally. Good agreement is seen. The proposed uniplanar EBG power/ground planes structure can be widely used in high speed integrated circuits.
