| Abstract(in English) | In electronic devices on which micro-controllers are equipped, electromagnetic radiation causes EMI and can be emitted efficiently when conductor patterns of printed circuit boards(PCBs)and wire-harnesses act as antennas. In particular, common-mode current, which is generated when a micro-controller is operating, is one of the main causes of EMI problems. 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 the power distribution network(PDN), and we can reduce the common-mode current. In this paper, the authors verified this reduction method on a package of a micro-controller LSI. As a result, the common mode was reduced at several frequencies also when the micro-controller is in program operation. |
