Different approaches to investigation of signal peak values localization in printed circuit board of autonomous

Importance of an investigation of specific aspects of ultrashort pulse propagation and voltage peak values localization along printed circuit board (PCB) multiconductor bus with different approaches (with fixed selection of an ultrashort pulse duration and with using an optimization) is highlighted. Trapezoidal ultrashort pulse propagation along the conductors of real PCB multiconductor bus was simulated. With the usage of genetic algorithms (GAs) an optimization of the whole ultrashort pulse duration and severally of the rise, top and fall durations was made by criteria of peak voltage maximization in the PCB bus. A signal maximum which is revealed with the fixed selection of the ultrashort pulse duration by 20% exceeds the steady state level. A crosstalk minimum value which is 39,8% of the steady state level is revealed and localized. A signal maximum which is revealed with the using of the optimization by 38% exceeds the steady state level. It is shown that significant signal excess is observed with decreasing of ultrashort pulse duration both for maximum and minimum. Also, localization of voltage peak values is inconstant: they appear in different parts of PCB bus including different PCB layers.
