Reducing various types of noise such as reflections, mode-conversion, return-path bounce, and crosstalk becomes a serious challenge in signal integrity designs of high data-rate interfaces. In this article, Dror Haviv focuses on the analysis and properties of the FEXT, presenting an alternative way to analyze the FEXT and its properties using the superposition theory of the differential signal and the common signal.

Inductance and resistance are fundamental to the design and analysis of Power Delivery Networks (PDNs). Excessive inductance and resistance can cause several severe power and signal integrity problems, as well as design failure. As we have seen, inductance can certainly be a confusing parameter. The type of the extracted resistance and inductance (loop or partial) depends on how the ports are connected to the model in the simulation. Consequently, their connection in the electrical circuit and the level of voltage details we can get from the simulation results will be determined. In many cases, it is required to know the voltage drop on the PWR path and on the GND path separately, therefore it is necessary to use partial inductances and resistances. The method of expressing SLI with partial inductances and the ideas behind it are briefly described in this paper.

Can common via structures transfer any data rate or are they limited with a defined bandwidth? If so, what limits its bandwidth? And what can be done when the bandwidth of the signal is greater than the bandwidth of the G-S-S-G structure? This technical feature from Dror Haviv explains.

Why does a low cost through-hole SMA have a lower bandwidth than a surface mount SMA? The answer will surprise you.
