High-Speed PCB Design: Simulation Analysis Reveals the Importance of Guard Ground Traces

2026-04-01

I have shared the simulation and testing methods for crosstalk on several occasions recently, and this article is written based on the previous research. Some topological structures in this article are unclear mainly because there are too many transmission line segments in the schematic, leading to blurry screenshots in the text. I will have further discussions with you on this topic when the opportunity arises.

Although many converters feature tri-state outputs/inputs, the associated registers are still on-chip. These can couple data pin signals into sensitive areas, making isolation buffers a sound design practice. In some cases, additional data buffers must be placed directly at the converter output on the analog ground plane for enhanced isolation.
