Based on the concept of localization, a novel array design etching electromagnetic band-gap (EBG) structures on both the power plane and ground plane in the region of noise source and noise-sensitive devices is first proposed to mitigate simultaneous switching noise (SSN). Then, a super-array design is proposed for better suppression. It has shown good performance in eliminating noise. The -55-dB suppression bandwidth can be broadened from 244 MHz to 20 GHz.
