How Return Path Discontinuity Amplifies Crosstalk in High Speed PCB
Return path discontinuity amplifies crosstalk in high speed PCB design by converting clean differential signals into noisy common-mode currents. This hidden mechanism creates large current loops that radiate magnetic fields, coupling into adjacent traces far more aggressively than standard crosstalk models predict. Understanding this amplification is critical for any engineer designing 10 Gbps+ digital systems….
