Crosstalk Between PCB Traces – Time and Frequency Domain Measurements, Part 2

In this article, we investigate the impact of a guard trace on crosstalk reduction and present measurements taken with the latest‑generation PCB, both in time and frequency domains.

Crosstalk between PCB Traces – Time and Frequency Domain Measurements, Part 1

This article is the first of a two-article series devoted to the topic of crosstalk between PCB traces. In Part 1 of the series, we vary circuit topology, i.e., the distance between traces and the distance to the ground plane.

Guard Trace Impact on Crosstalk Between PCB Traces

Adding a guard trace between PCB traces sounds like a simple crosstalk fix — but grounding it wrong can actually make interference worse, not better. See how capacitive and inductive coupling respond differently to grounding placement, and why one counterintuitive result changes the design approach.
