PC Board Grounding to Control Noise, EMI and Signal Integrity

When time-varying (AC) signals travel in the transmission lines of a board, state-changing electric and magnetic fields are present. These fields, when not controlled, are the source of noise and... [more]

Novel Power Distribution System Design

This presentation will present a simple EM physics and geometry-based approach to designing power distribution networks on PCBs. From input power connection to the IC die, the simple rules discussed... [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]

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]
