• Electromagnetic bandgap (EBG)
• IR drop
• signal integrity (SI)
• simultaneous switching noise (SSN)

In the paper, a novel structure for suppressing simultaneous switching noise is proposed based on the coplanar electromagnetic bandgap (EBG) power plane. The proposed EBG structure is designed on the basis of periodic L-bridge which is inserted by a small L-bridge cell with windmill-shaped slits where the power port is located. Simulation and measurement results show that the presented structure possesses a wide stop band ranging from 510 MHz to 10.35 GHz at -40 dB suppression of the bandgap depth. Then, the IR drop and the dc resistance are accurately investigated by the simulation software of CST. Finally, time-domain simulation results show that the structure in high-speed circuit is met with signal integrity.
