An examination of forward crosstalk in microstrip transmission lines is presented through a computer simulation using SPICE. A non-resistive lumped L-C transmission line model is modified to include capacitive and inductive coupling from adjacent lines. Two adjacent microstrip transmission lines are modeled, and simulation results in both the time and frequency domains are shown. The time domain or transient analysis looks at the effect of rise times on crosstalk. Rise times in the range of 100 to 1000 nanoseconds (ns) are considered. The frequency analysis shows the crosstalk frequency response over the range of 100 to 1600 kilohertz (kHz). The effects of line spacing to dielectric height ratios, line width to dielectric height ratios, and line terminations are shown. A correlation of rise time to equivalent crosstalk frequency using crosstalk magnitude as a common point of reference is performed, and the line geometry and termination effects upon the correlation are explored.
