| Abstract(in English) | Recently, the PCB with multi-layer substrate (Multi-layer PCB) is extensively used with the trend of small size and high density of the electronic equipment. However, SI/PI problems such as resonances between the power and ground layers in the Multi-layer PCB may occur. In this study, a three-layer board consists of signal-power-ground layers with coupled two lines is considered. An equivalent circuit model is proposed for the coupled lines while considering the effect of the resonance between the power-ground layers. The validity of the equivalent circuit model is checked by comparing the transmission characteristics of differential signaling and single-ended signaling with the full-wave simulations. The transmission characteristics of differential signaling are also examined by changing the coupling degree. It is shown that the equivalent circuit model is valid, and if two lines are tightly coupled, the effect of the resonance to the transmission characteristics is small. |
