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 ...

As you probably know, processors – and most other digital technology – are made up of transistors. The simplest way to think of a transistor is as a controllable switch with three pins. When the gate ...

Editor's Note: An updated version of this information can be found here. What exactly is computer-numerical-controlled (CNC) machining? It’s a means to make parts by removing material via high-speed, ...

In the first of a multi-part series on how to design a custom chip for under $1,000, our Analog Editor gets you started with a Magnificent 7 list of textbooks. TinyTapeout offers a course that ...

Part 1 of this series focuses on high-performance electronic loads for testing power supplies that have low output voltage and high current. It describes the necessity for special electronic loads, ...

Part 1 of this series described how digital signals propagate through PC boards, and Part 2 described specific board stack-up designs to achieve low EMI. Part 3 will address partitioning of circuit ...
