Summary:
Abstract In this paper, a novel power plane is proposed using the novel S-shaped bridge electromagnetic bandgap (EBG) structure to isolate the ground bounce noise (GBN) and ultra-wideband suppression of simultaneous switching noise (SSN) in high-speed circuit. The novel S-shaped bridge effectively increases the inductance between two adjacent unit cells. And the ripples are held down by open stub to get higher attenuation level. The stop-band of -30 dB suppression bandwidth of the design |S31| is from 114 MHz to 8.5 GHz, The results of simulation and experiment will be presented to verify the good performance, and that it covers the entire noise band.
