Abstract
According to electromagnetic bandgap (EBG) structure of the simultaneous switching noise (SSN) suppression mechanism and coplanar EBG structure equivalent circuit model, a novel structure of Meander-L Bridge is proposed for SSN suppression in high-speed circuits. Simulation and measurement results show that the stopband ranging from 210MHz to 20GHz at −30 dB suppression of the bandgap depth. Furthermore, the suppression bandwidth is more than 19.79GHz to achieve the ultra-wideband SSN suppression. Moreover, time-domain simulation results show that the structure in high-speed circuits is met with signal integrity.
