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]

Hair-Raising Footprint Horror Stories – and How to Avoid Them

When creating libraries, standards are crucial for maintaining consistency, accuracy, and reliability. Yet, even with rigid standards in place, mistakes inevitably creep into such a detail-oriented... [more]

From DC to AC - Power Integrity and Decoupling Primer for PCB Designers

Supply voltages decrease with every new silicon generation, contributing as well to the goal of reducing power consumption of our electronics. Coupled with the resulting shrinking noise margins for... [more]
