Developing Prototype Circuits from Home: Part 5, Grounds, References, and Returns
Scott Deuty 10/29/2015 Post a comment
In this fifth segment, the subject of grounding, references and returns will be addressed. Often times a return path is treated like the drains and sewer lines exiting a building or home. Once the electrons (waste) are in the ground (sewage), they are out of sight and out of mind. For circuits, this can cause issues especially in sensitive signals such as control loops. Even at the gate drive level, interactions of currents can cause false signals.
ESD Protection For High-Speed Serial Buses
Paul Pickering 10/26/2015 1 comment
ESD has been around for a long time – probably since shortly after the Big Bang. For most of human existence, it's made itself known by macro effects such as static cling and mildly shocking encounters with metal objects. Since the advent of semiconductors, though, protecting electronic devices against ESD damage has been a prime goal of manufacturers; failure to do so can have catastrophic consequences
Who is Really the First to Invent Anything?
Scott Elder 10/26/2015 11 comments
>“First to invent” is a term of art used under previous United States (U.S.) patent law to define who deserved a U.S. patent. Regardless of your opinion about the recent U.S. patent law changes, from a practical sense it is very hard, if not impossible, to define who is the first to invent anything.
Quantenna, Freescale and 10 G Wave 3 Wi-Fi
Steve Taranovich 10/25/2015 4 comments
The IBC show in Amsterdam this year inspired the re-thinking of Access Point architecture. Quantenna led the pack with their newest IC solution for increasing the MIMO order (i.e. the number of spatial streams per given channel) in their True 8x8TM radio configuration IC chip for 10G Wave 3 Wi-fi—the first in the industry

One's mind may recall the pyramids' potential methods of construction, but again, who could produce at that time such an intense sonowave? Rather impossible. But again......
Meet Ioannis (John) Piliounis, a new contributor to Planet Analog
Steve Taranovich 10/19/2015 Post a comment
I want to introduce you to a fellow enthusiast of Nikola Tesla’s life and work. John Piliounis and I have been communicating over the last two and a half years via e-mail on various technical/scientific subjects that I believe will be of great interest to you, our Planet Analog audience. I will be bringing you some of these blogs going forward.
Lane changing decisions and beyond: Do we trust them yet?
Steve Taranovich 10/19/2015 8 comments
Tesla Motors recently introduced their 7.0 “Autopilot” software update for their Model S sedan with lane change and auto-steer capability. Of course, at this point, Tesla warns that the driver, and not Tesla or its software and systems, is still responsible for the ultimate control of the car.
Constraint-driven Analog Placement and Routing
Keith Sabine 10/19/2015 Post a comment
Although digital design productivity has improved massively since the introduction of synthesis, advanced place and route and timing-driven design, analog design still relies on circuit simulation, manual layout and verification.
Medical advances by NASA in Space that benefit Earth
Steve Taranovich 10/7/2015 Post a comment
NASA has some of the best scientists and engineers in the world that are challenged to develop manned and unmanned exploration systems that can travel in deep space searching for an answer to “What is out there” while stretching our capabilities to beyond the limits of our imagination
Twiddling the Ethics Knob
Ken Coffman 10/6/2015 2 comments
I’ve been thinking about ethics recently, but not the generic kind represented by violations like taking a company pen home. And who among us can claim to be purists? I can’t—I have plenty of company pens laying around my office. And, truth-be-told, my war stories get more polished and elaborate each year. Let the stones in my glass house be unthrown.
Electromechanical Displays, Part 1: The Nipkow Disk
Dennis Feucht 10/1/2015 4 comments
One of the more impressive presentations of a gadget at a recent Maker Fair was a floor-mounted four-hoop device with LEDs along each hoop. The hoops were circular in shape as though they were the longitude lines on a globe. When the contraption was rotated and the LEDs driven under computer-based control, a 3D display appeared. The resolution was visibly low but at inventor shows, it is more the idea that counts than its immediate refinement.
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
