Study of Applying S-bridge Electromagnetic Band Gap Structure for Simultaneous Switch Noise Suppression

A new S-bridge electromagnetic band gap structure(EBG) is designed,and the proposed S-bridged EBG power plane has been fabricated simultaneously with a conventional parallel plate power plane and the L-bridged EBG power plane for the comparison.The results shown that using S-bridged electromagnetic band gap structure can improve the SSN suppression bandwidth,moreover,it can reduce the number of local decoupling capacitors.
