| Abstract(in English) | The authors have been proposed a method to reduce the common-mode current flowing on a wire harness attached to a PCB. In this method, chip inductors are equipped on power and/or ground lines on a PCB to control balance of impedance of the power distribution network, and we can reduce the common-mode current. In this paper, the authors apply this reduction method to LSI package, and propose new structure of the LSI package with floating conductor, which is called cover metal. We reduced the common-mode voltage about 40 dB because we used the new package with the cover metal and we selected apposite inductances on the power and ground line on the package. |
