In a previous article, I discussed the common mode coupling on the PoE (Power Over Ethernet) DCDC converter that I discussed a few months...

EMC is considered by many to be a "black magic" for a number of reasons. In some cases, it may be the case that you obtain unexpected...

Today, it is common for a product to contain a motherboard and several daughter boards. In the following example, let us imagine that we...

A couple of months ago, I was testing EMC for a medical product. As the product is enclosed within a metallic enclosure, I was concerned...

I visited Scotland on holiday, a beautiful country! There is so much history in Edinburgh, and I also enjoyed visiting Glasgow. It is...

A few years ago, I worked on digital radio for a customer. It was a very complex design, but the reward for an electronic engineer such...

Some time ago, I wrote a blog post about the design technique I use when I am solving EMC emissions for clients when I am working on...

Those of you who are reading my post know that there is not much 'black magic' behind EMC and that there is always an explanation for why...

I designed my first general I/O PCI card when I was a student (a few years ago now :-)). The PCI card was part of my thesis, and the...

As we have seen in parts 1, 2, and 3, the input current loop of a DCDC converter affects both conductive and radiated emissions....

In the process of creating a new product from scratch, I always add components that I may not need in production when I am designing it....

To avoid EMI and crosstalk on both PCB traces and connectors, it is crucial to understand the return path current. Previously, I...

I had the pleasure of working with a customer a few years ago, who was ready to launch his product on the market. My suggestion was to go...

It was my pleasure to assist a startup company in passing EMC last month. The company now has its CE mark on their product and I am...

When we design electronics, there are a few things we shouldn't skip. Often, CEOs and CTOs pressure us to design things quickly. But what...

When we place our bypass capacitors on a PCB, there are several factors that may affect the series inductance of the capacitor ESL when...

I spent several stimulating days last week performing EMC testing on one of my most challenging designs in the past two years. This is...

Recently, a customer contacted me about the possibility of "fixing" their design from the standpoint of EMC. The board may function...

Have you ever seen corrosion on the solder joints on an old PCB? Or on the aluminium side of a power supply? Why we do have corrosion,...

A few years ago I was doing EMC testing for a product I designed myself. The emissions were so low that at some point the EMC house...
