S-Parameter Measurements and Errors in Power Integrity No matter where you look, it seems S-parameters never go away! They are mandatory tools for understanding some systems, such as an interconnect or antenna, while other network parameters can sometimes give a better conceptual understanding of electrical behavior. These parameters are normally reserved for signal integrity among electronics engineers, but if you look hard enough, you’ll find that S-parameters are also used for power integrity Read Article Smart Micro Fan Controller If you’ve ever had to wear eye protection for an extended period of time, especially if you have prescription inserts in that eye protection, you’ve probably noticed fogging can be a major issue. Last year I designed and 3D printed a small fan unit that mounts a 25mm x 25mm x 10mm fan on each side of a military eye protection. It directs a small flow of air over the inside of the lenses and keeps them clear even during physical exertion on cool Read Article Complete Guide to PCB Component and Design Reuse in the Cloud Isaac Newton once said "If I have seen further it is by standing on the shoulders of Giants." Not all designs need to be remade from scratch, and if you organize your designs properly you can easily reuse your old design data in a new project. PCB design reuse practices are great for cutting down design time and ensuring all your products live up to the same level of quality. It’s all about making sure the knowledge you’ve gained from building Read Article Create a Buck-Boost Power Supply In this series of articles, we’re looking at the design and implementation of the main types of power regulators and converters you might use in an electronics project. I gave a graduate engineer who I mentor a series of requirements to demonstrate each of these types and have recorded the results here so you can work through the same exercises and hopefully come up with the same results. The next switching regulator is the last in our switching Read Article How to Design a PCB for a Boost Converter In this series of articles, we’re looking at the design and implementation of the main types of power regulators and converters you might use in an electronics project. I gave a graduate engineer who I mentor a series of requirements to demonstrate each of these types and have recorded the results here so you can work through the same exercises and hopefully come up with the same results. For the next switching power supply project from my Read Article How to Make Advanced BLDC Motor Controllers In this project article, we’re going to be taking a different approach to my typical project. Driving a brushless motor is relatively simple from a schematic perspective; however, there is a large amount of theory about brushless direct current motors that you need to understand to be successful. If you only have experience with brushed motors or no experience with driving motors at all, we will be covering everything you need to know. You can Read Article Controlling Crosstalk In Connector Pinouts This article will describe this type of crosstalk, the types of disruptions it causes, wherein the design cycle it needs to be factored in and how it can be successfully controlled.

Here’s how you can use Altium 365’s cloud platform to share and access Gerbers from project revisions. Read Article From RC to Atomic Clocks: All Clock Sources In almost modern circuits, especially whenever digital circuitry is involved, you will find some kind of clock source. All clock sources present a series of tradeoffs regarding stability, reliability, size, power consumption and cost. Luckily for us, such tradeoffs are relatively simple and can be explained almost fully within this single article. We’ll discuss the pros and cons of each clock source, from the RC in a 555-powered oscillator, to a Read Article What They Don't Teach You About Capacitors In engineering, we often adopt hundreds of mental shortcuts in order to keep the complexity of the topics we tackle to a manageable level. If we were to run a quantum-physics simulation every time we flash an LED, we would never get anything done. Yet, many of these shortcuts and rules-of-thumb were created in times past , when the electronics industry was radically different than what it is now. Today, we are going to unlearn what a capacitor is Read Article What They Don’t Teach You About Solder Fluxes on PCBs Introduction As engineers, we sometimes sit high on our pillowy chairs, looking at the nitty and gritty of the industry — such as the fabrication of the PCB — with a bit of nonchalance. The truth of the matter is, when studied in-depth, PCB fabrication is an extremely complex technological topic that deserves recognition as the most fundamental part of PCB engineering. Unless connectors, conductive adhesive, wire-bonding, or zebra-tape are used Read Article LearnEMC CEO Todd Hubing on Engineering Consulting Services Kella Knack interviews Dr. Todd Hubing a top EMC expert. They discussed topics about the design challenges in Automotive Industry and tackled EMC concerns at the board level.

In this blog post, expert Mark Harris shares his top picks of high performance and best value for money CAD computers. Read Article Thought Leader Article, Dave Huntley, PDF Solutions In an ideal world where ideal products are developed, we would never have any issues resulting from any step in the design, fabrication, assembly, test and field operation processes. But in the real product development world that we inhabit, it is a fact that some level of undesired quality and reliability issues will occur. We continually look for novel ways to address these manufacturing issues especially as the components and the PCBs where Read Article Interference Amplitude Distortion I’ve talked about COM and channel analysis in previous blogs, and I’d like to continue the discussion with more visual aids and some example code to enable readers to do some analysis themselves. To start, let’s review what COM is and a high level overview of how COM is calculated. COM is a signal-to-noise ratio of voltage at a point in time. The point in time is the sampling point, and the available signal is the voltage of the pulse response at Read Article PCB Changes: Tips for Updating Old PCB Designs with New Parts Follow our tips for updating old PCB designs with new parts.
