Abstract: This tutorial discusses proper printed-circuit board (PCB) grounding for mixed-signal designs. For most applications a simple method without cuts in the ground plane allows for successful ...

In this article, we continue our discussion on the importance of grounding when installing LED lighting equipment. Part 1 of this three-part series focuses on the ground plane of the printed circuit ...

Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...

Considerations for dividing analog and digital blocks. Decoupling techniques. Breaking down the board layers. How best to deal with grounding. Similar to building a house, it’s essential to create a ...

The best news when you power up a prototype supply board for the very first time is when it not only works, but also runs quiet and cool. Unfortunately, this does not always happen. A common problem ...

Grounding problems and unwanted noise in electrical systems can often lead to insanity. It can seem like there’s no method to the madness when an electrical “gremlin” caused by one of these things ...

We’ve often heard you should do everything twice. The first time is to learn what you need to do, and the second time is to do it right. We bet [Ian Carey] would agree after taking his old linear ...

Engineers must be wary of safety, electromagnetic-compatibility, and thermal-management factors when installing open-frame and U-channel power supplies. Typically, power supplies are supplied in what ...

My friend's dad has some very strage problems with his PC. He took it to his ISP to have them diagnose an unrelated problem (software-related) several days ago. Ever since he plugged it back in at ...
