This article describes a practical way to improve signal integrity of typical interfaces on the PCB when using external ESD devices.

This is the second article of a two-article series devoted to the return current distribution in a PCB microstrip line configuration.

This is the first article of a two-article series devoted to the return current distribution in a 2-layer FR-4 PCB microstrip line configuration with a solid reference plane.

There are many books and other reference materials available that describe proper printed circuit...

Should the reference (i.e., ground) plane be split into two separate sections and a ferrite bead installed between them to prevent unwanted radio frequency emissions? Let’s examine why this practice is not a good idea and should be avoided at all costs.

This article provides insight into how shielding is used in product development, in particular the effectiveness of shielding when it is applied at the PCB level. 

Low-cost designs are often an underserved and challenging part of a layout engineer’s career and getting increasingly complicated.

The mirror technique is a very old technique to be used with PCBs when failing in radiated EMC tests. An easy solution to avoid changes in layout if the technique can be applied to your product.

Software tools can give the EMC engineer a better chance to pass EMC requirements the first time.

It is very common for people doing simulations to make a measurement of a similar set up to validate the simulation. This is a reasonable precaution since modern simulation tools will give a very accurate answer to whatever question it is asked.
