| Abstract(in English) | Power bus resonance in a multilayer printed circuit board(PCB) is one of the major source of radiated EMI. Power island structures that are completely cut from other parts of the power bus by gaps are well known to be used for isolating the power bus noise and mitigating the radiated EMI. To ensure retain paths of signal lines, however, it is necessary to connect partially the island to other parts of the power bus. Isolation effect of such imperfect island structure is, of course, worse than that of a complete island structure. This report shows that the isolation effect of an imperfect island structure can be improved by setting decoupling capacitors to specific locations of the island. The effects of the number and the separation of the decoupling capacitors were studied by simulations. The validity of the simulation results was demonstrated by good agreements to measurements. |
