Backroads or Highway: Managing PCB Power Distribution with a PDN Analyzer
Who hasn’t been caught daydreaming out the window, overlooking the lines of cars on the freeway at a standstill, wondering about easier or more effective ways of getting to your job on time? And even then, sometimes the alternate routes aren’t always the fastest—there could be road construction, or an event going on which makes you have to re-route even more. At that point, most tend to throw all hopes for getting to work on time out the window

Boats With The Current: Microstrip and Stripline Transmission Lines Trade-offs
In F. Scott Fitzgerald’s The Great Gatsby, the narrator, Nick Carraway, is torn between infiltrating the notorious elite social circles by attending his neighbor Jay Gatsby’s infamous mansion parties in Long Island, New York and establishing himself on the east coast in a finance career. It can be easy to have an understanding of The Great Gatsby through its context - the roaring twenties, flappers, prohibition - it wouldn’t do justice to any of

Design for Electromagnetic Compatibility in PCB: Let Your Revels Never End
What if William Shakespeare worked as an electrical engineer instead of a poet and playwright? If electronics existed during the mid-to-late sixteenth century, the Bard may have studied the impact of electromagnetic interference (EMI) on circuits and the need for electromagnetic compatibility (EMC). After all, he wrote about his fascination with noise in The Tempest: “Be not afeard; the isle is full of noises, Sounds, and sweet airs, that give

Omer Mahgoub from Square Kilometer Array (SKA) Africa and PCB Design for Astronomy
Judy Warner: Omer, will you please share what the SKA is, what countries are involved, and what purpose it serves? Omer Mahgoub: The SKA (Square Kilometre Array) is an international effort to build the world's largest radio telescope, with a total collecting area of 1 square kilometer and located on two continents (Africa and Australia). Organizations from 10 countries are members of the SKA: Australia, Canada, China, India, Italy, New Zealand

RF Interference Prevention and RF PCB Design in the Internet of Things
Have you ever been to a party where there was so much noise you could barely hear yourself think? I’m a dedicated introvert, but sometimes my friends lure me out to such gatherings with promises that it will be “very relaxed.” They never are, and I don’t seem to learn. It’s times like those that I wish it was socially acceptable to wear noise-canceling headphones to such events. In the world of electronics, the burgeoning Internet of Things (IoT)

Introduction to High Speed PCB Designing: Is FR-4 the Best High Speed Material Choice for High Speed PCB Design?
We’ve all been there at one time or another when we’re tasked with a project that lies outside our comfort zone. For me, that day came when my boss asked me to design a high speed board. While I considered myself to be a somewhat experienced PCB designer, I knew that high speed PCB design has many restrictions that you do not normally encounter when you’re designing an average circuit. Initially I invested time into making my schematics

Digital Player Grounding: How a Single Ground Connection Messed up 100 Units of MP3 Players
Technology is pretty great and it has definitely made certain things in life easier. However, when you’re juggling parenting, coding, electronics design and occasionally writing an article like this. Sometimes even the coolest apps can’t mitigate the stress we experience in a day. For example, this morning I accidentally mistook salt for sugar and mixed it into my child’s favorite porridge. One small mistake on my part and suddenly my 5-year-old

Semiconductor Fibers: What Will Replace Fiber Optic Cable Transmission Lines?
The Internet is a strange and wonderful place. I grew up at the end of the age of dial-up Internet when chat rooms were all the rage. Now, I occasionally enjoy using the Internet to play some online games, which was impossible back then. My telephone router and its copper network could barely support enough bandwidth to load an image. Now our networks have been upgraded with blazing fast fiber optics. While these communication systems are

PCB Ringing: What Causes and How to Reduce Ringing In Circuit Boards
Digital circuits are particularly sensitive to ringing effects. Editorial credit: Dikiiy / Shutterstock.com In my very first electrical engineering lab, we built a printed circuit to debounce the output of a switch. I remember seeing the original jumpy signal and then the debounced output on the screen of an oscilloscope. I felt a profound sense of unease that something so innocuous in our lives could be so...messy. It’s a good thing that my

The Most Important Features for PCB Layout Software Comparison
Have you ever gone to a used car dealership and tried to get a good deal on a car? It’s nearly impossible for anyone but a mechanic. When I went I ended up with a choice between two cars that seemed nearly identical to me, except for their price. I picked the cheaper one and took it to a local shop, and found out that I’d chosen a jalopy. Sometimes choosing PCB design software can feel the same way. You use a free program or spend some money on

Pros and Cons of Different High-Frequency Transmission Line Types
You already know that dating is something I struggle with. After my failed attempts at blind dates and speed dating, I decided it was time to try online dating. I found a nice woman who said she was my age and set up a date. Upon arrival, I found out that I’d been catfished--that wasn’t actually her in the picture! Needless to say, it didn’t go well. It made me realize that I should have done a bit more research about my date and online

High-Speed PCB Differential Pair Routing to Preserve Signal Integrity
Proper routing of differential pairs in high speed digital circuits is necessary for preserving signal integrity in PCBs. Some other items to consider when looking at your PCB, may be the ferrite bead or decoupling capacitor. However today, let's discuss some things to set you on the right path. Follow these differential pair routing guidelines and leave your EMI troubles behind. I once went on a blind date with a woman who, unbeknownst to me
