Transmission line losses—driven by skin effect and dielectric properties—play a critical role in degrading high-speed signal integrity and eye performance.
Transmission line loss directly affects eye diagram quality, with around −12 dB at Nyquist marking the limit before signal integrity rapidly degrades without equalization.
Foundational and advanced concepts for maintaining clean, reliable signals in high-speed designs. Covers measurement techniques, common pitfalls, and practical approaches to identifying and mitigating signal degradation in order to maintain signal integrity and power integrity in electrical designs.

This article explains how PDN design, probing method, and measurement location influence power rail noise—and why board-level measurements can be misleading.
This tutorial explains how quiet I/O probing reveals true on-die rail compression—often far greater than what traditional board-level measurements show.
Accurate power-rail noise measurement requires handling tiny signals on large DC offsets, best achieved with active probes and proper impedance management.
RF pickup can introduce misleading noise into power-rail measurements, but proper shielding and coaxial connections can dramatically reduce interference and reveal true signal behavior.
This practical walkthrough shows how to measure and diagnose ground bounce using oscilloscope techniques, quiet-low sense lines, and controlled I/O switching scenarios.
Ground bounce occurs when simultaneous switching currents flow through shared inductance in IC packages, creating voltage noise that can lead to digital bit errors.
