PC-board layout sets the functional, electromagnetic interference (EMI), and thermal behavior of a power supply. Good layout from first prototyping on actually saves significant resources in EMI ...

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 ...

As an engineer who enjoys tinkering on various hobbyist projects, I have occasion to draw schematics and (when the bank account allows it) order PC boards. I've tried several different schematic ...

Part 1 of this series described how digital signals propagate through PC boards [Refs. 1, 2, 5, 6]. In part 2, we look at specific board designs to achieve low EMI. The biggest issue I see in my ...
