摘要

摘要--考虑了计算多导传输线单位长度参数矩阵和特性的特点。提出了计算多导传输线单位长度主要参数矩阵的方法。制定了电容矩阵计算精度的标准。我们注意到,要正确估计传输线中传播信号的失真,就必须准确考虑传输线导体之间的相互影响。多芯传输线的单位长度参数对其有源导体末端的响应和眼图的影响已经得到证实。研究了从极端导体到传输线横截面边界的距离对其电容矩阵计算精度的影响。利用矩量法,研究表明已知的确定这些距离的方法并不总能得出准确或有效的结果。以几条具有不同数量介质层和导体的传输线为例,以及有屏蔽层和无屏蔽层的传输线,确定了能够准确有效计算其电容矩阵的最小距离值。

On the Features of Calculating per-Unit-Length Parameters and Characteristics of Multiconductor Transmission Lines

Abstract

The features of calculating the matrices of per-unit-length parameters and characteristics of multiconductor transmission lines have been considered. The method of calculation of the matrices of primary per-unit-length parameters of multiconductor transmission lines has been presented. The criteria for the accuracy of the calculation of the capacitance matrix have been formulated. It has been noted that it is necessary to accurately account for the mutual influence between the transmission line conductors for a correct estimation of the distortions of the signals propagated in it. The influence of the per-unit-length parameters of multiconductor transmission lines on responses and eye diagrams at the end of their active conductors has been demonstrated. The influence of the distances from the extreme conductors to the boundaries of the cross-sections of transmission lines on the accuracy of calculating their capacitance matrices has been studied. Using the method of moments, it has been shown that known approaches to determining these distances do not always give accurate or efficient results. On the example of several transmission lines with different numbers of dielectric layers and conductors, as well as with the shield and without it, the minimum values of this distance at which it is possible to achieve an accurate and efficient calculation of their capacitance matrices have been determined.
