IEICE EMC'14/TIKYO, 14A2-B2 ページ: 342-345キーワード：EMC, 電源雑音，アナログ・デジタル混載，抵抗付加概要：アナログ回路，デジタル回路混載のプリント配線板おいて，基板端部の電源層間に抵抗とコンデンサからなる複合部品を付加することによって, デジタル側からのアナログ側への電源雑音の伝搬を低減する技術である。抄録：In analog-digital mixed circuit boards , noises from the digital side to the analog side through GND power supply layer is one of the problems. As one of the methods to reduce noise, slot type GND power supply layer is used. It is to divide GND power supply layer with slot. However, this method has problems. One of the problems is impedance mismatch on the signal line between the analog and digital. And, another problem is increasing the crosstalk between parallel signal line. Therefore, we adjusted to attaching resistor around the circuit board. This Attached Resistor Method is proposal technique as a method reducing radiation noise from power supply layers. As a result evaluation by the simulation, we were able to make sure the effectiveness in reduction noise.英語フィールド
