Abstract: This paper presents the calculation of the differential impedance, the velocity of propagation, and the worst-case near-end crosstalk coefficient of the cross sections of transmission lines by using a computer-aided design tool. The cross sections embedded in this tool are commonly seen in electrical connector design, but not in printed circuit board design due to their different fabrication processes. Several designs are studied and the important results are presented. Some charts that illustrate the relationship between the electrical parameters and the geometries of the transmission lines are shown, which allow the designers to perform a quick initial design.
Keywords: differential impedance; propagation velocity; crosstalk coefficient; electrical connectors; transmission lines; computer-aided design; CAD.
