本文提出了一个方面的同步开关噪声（SSN）的CMOS驱动器的封装与电源分配平面。该分析考虑了配电平面和信号迹线之间的相互作用。它们之间的耦合对噪声有显著影响，必须加以考虑。的信号导体和电流路径之间的相互作用的电源分配平面的模型。信号导体的存在被认为对SSN有重大影响。噪声的大小在很大程度上取决于信号导体与电源和接地层引脚连接的相对位置。彼此足够接近的电源层和接地层也具有显著的互感耦合。这种耦合将导致在两个分布平面中观察到噪声，即使开关电流仅在一个平面中流动。这种效果得到了解释。<<ETX>>
The paper presents an aspect of Simultaneous Switching Noise (SSN) for CMOS drivers in packages with power distribution planes. The analysis takes into account the interactions between power distribution planes and signal traces. Coupling between these have a significant effect on the noise and must be taken into account. A model for the interaction between the signal conductors and the current paths in the power distribution planes is presented. The presence of the signal conductors is seen to have a significant impact on the SSN. The magnitude of the noise is strongly dependent on the relative positions of the signal conductors and the power and ground plane pin connections. Power and ground planes sufficiently close to each other also have significant mutual inductive coupling. This coupling will cause noise to be observed in both distribution planes, even though switching current flows in only one plane. This effect is explained.<<ETX>>
