Causes of Signal Degradation in PCB Transmission Lines

Signal degradation on PCB transmission lines manifests in many forms: undershoot, overshoot, ringing, pulse shape distortion, switching noise, attenuation, ground bounce, skew, etc. All these can be... [more]

Does a Differential Pair Need a Return Plane?

A differential pair is any two transmission lines. When each transmission line has a return plane, its pretty clear how the differential impedance is related to the geometry. But what if there is no... [more]
