Greetings! I am stuck on understanding a contradiction - perhaps someone could "unstick" me? It is understood that (at high frequencies) the dielectric losses in a pwb dominates the losses of a transmission line. However, I have read in various publications that increasing the trace widths improves the jitter performance of a high speed serial link. I would have thought that as a trace width increases the effects of the dielectrics would be exacerbated. How does increasing the width of a trace improve the DJ of the link?
