Models for circuit simulators to analyze crosstalk and radiation into wires

A procedure is presented for analyzing digital pulse distortion, unintentional electromagnetic coupling (crosstalk), and the pickup of an incident electromagnetic field by transmission lines, using suitable models for commercial circuit simulators such as ASTAP, SPICE, and SABER. Transmission-line effects and field-to-cable coupling are represented in the circuit simulator by voltage sources for AC and transient analysis. AC computations can be done with distributed parameters, instead of lumped parameters, producing good accuracy and saving time. This type of analysis is very useful in the case of a periodic signal and linear loads. A description of these models and a comparison with experimental results are given.<
