When Engineers' Worlds Collide
Jason Bowden 7/31/2013 15 comments
There are regular conflicts between the different engineering groups associated with new product development. When this occurs, how are the conflicts resolved? Who wins? And at what cost?
Where Is Analog Integration Going?
Tom Terlizzi 7/29/2013 26 comments
Analog integration -- from field programmable analog arrays (FPAA) to System in Package (SiP) and System on Chip (SoC) -- analog design engineers have more and better choices. A brief and approximate history of analog integration techniques.
Graceful Degradation Is Good
Brian Bailey 7/26/2013 13 comments
Digital processing circuitry as used in cameras, CD players, HDTV receivers, and cars has an annoying tendency to go from working fine to working not at all. There is no graceful transition where performance fades away.
The Analog Designer Hall of Fame
Jack Shandle 7/25/2013 26 comments
If analog is truly a unique combination of technology and art, shouldn't there be an Analog Hall of Fame? If so, how does one go about choosing the inductees?
Filter Techniques in Circuit Integration
Steve Taranovich 7/23/2013 10 comments
Techniques for putting all of the active filter circuitry on an IC are now available. That includes MEMS devices and all reactive elements -- the capacitors and the inductors -- or their gyrated equivalent.
Caution: Wide Load!

Current sensing should be easy to do -- and it is, on paper. But in the real world, things don't always work out quite as easily. Here are some problem solving design tips.
Top-Down vs. Bottom-Up Behavioral Model
Brian Bailey 7/16/2013 5 comments
To create a proper model for the analog device you're creating, you must clarify why you are creating the model. What value does it serve? What problem does it address? Who will use the model and when?
Technical Support Primer
Parker Dorris 7/12/2013 3 comments
Engineers design things, but they also solve problems. How they go about that ranges from Kinderspiel to Sturm und Drang.
Magnetic Field Sensors
William Murray 7/12/2013 17 comments
Magnetic fields can be detected and measured with a variety of different sensors. Some of the devices exhibit variations in resistance; some put out a varying voltage or current. Some are inexpensive, general purpose devices. Others are the exact opposite.
Between Discrete & Integrated Circuits
Dennis Feucht 7/10/2013 11 comments
Somewhere in time and the manufacturing space, there existed circuit devices that were more sophisticated and complex than discrete components, but not quite integrated circuits. They were called hybrids. Today's surface-mount technology draws from them.
Component Count & Reliability
William Murray 7/8/2013 6 comments
There are factors beyond simply using good quality components that will affect your products reliability. Statistically, the number of components and interconnections will have a direct effect.
FinFETs & Analog
Brian Bailey 7/5/2013 4 comments
The FinFET -- savior or just another gimmick? Will the device be useful in analog applications or only in digital?
William Murray 7/4/2013 6 comments
Designing inductors and transformers used to be difficult and labor intensive with lots of trial and error. It's a lot easier now.
This Is Really Happening
Peter Zawistowski 7/3/2013 11 comments
Is analog video finally going extinct? Quite likely, if the controlling agency (which knows what's good for us) has its way.
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.
