The STEM shortage: real or not?

We hear a lot about this "crisis," but whether it exists and, if so, to what extent, may be an unanswerable question.
“Free” DCR Current Sensing Must Die
Ken Coffman  
9/23/2016   Post a comment
A popular ‘free’ method in a buck converter is DCR current sensing. It’s free in the sense that no added cost or power loss is added to the design, but these circuits are notoriously inaccurate, particularly when small, low-ESR inductors are used.

Signal Chain Basics #116: Combining signals for better performance
Signal Chain Basics  
9/13/2016   2 comments
When the phase noise performance is just not good enough, one possibility is to combine two or more signals that are in phase to generate a better phase noise signal. This concept applies to the scenario of combining two sides of a differential output to form a single-ended output or the combination of signals from two semiconductor chips of the same type and configuration.
Vaporware for the Internet of Things
Scott Elder  
9/13/2016   2 comments
For those who aren’t familiar with the term vaporware, it simply means hardware or software that is heavily promoted, but not for sale. Like any vapor, it exists only in air. This seems to be the case with narrow band Long Term Evolution (LTE) modems for the Internet of Things (IoT).

How Technology Is Lost: Stories from Ancient and Recent History
Dennis Feucht  
9/13/2016   7 comments
In our time of global interaction, could technology be lost by war or other social factors? Loss need not be caused by a social event but merely by environmental factors. A trend in information technology is toward increasing fragility.
Gas Discharge Tubes: Old Protection in a New Bottle--Literally

Sometimes the "old" is more than merely "new again", but instead is the only viable solution to a challenging technical problem.
Autonomous vehicles supporting futuristic infrastructures
Garima Jain  
9/12/2016   Post a comment
The world of automotive today buzzes with three words, electric cars, car sharing or licensing and autonomous cars. It is pretty interesting to see the way the world is shaping up to accommodate these trends and how these trends are actually shaping up because of the direction in which the human civilization is headed.
Power Integrity for IoT Components
Raj Nair  
9/6/2016   2 comments
A prevailing assumption in the industry, EDA in particular, is that IoT chips are less of a challenge. Technology and IP integrated are well known. The chips are not leading edge in the fabrication processes used. Tools that met the needs of prior fabrication processes hence suffice to meet the needs of IoT chips. It is just a matter of designing to the specific application
Using Excel as a Design Aid in Lookup Tables
Aubrey Kagan  
9/6/2016   Post a comment
It is no secret to my legions of followers (Hi, Mom!) that I enjoy working with Cypress’ PSoC architecture especially the PSoC4 and PSoC5 varieties. Let me state up front that this blog is far more about the usage of Excel than about the PSoC, so don’t tune out just yet. I have written quite a bit on the application of Microsoft Excel to different aspects of electronics, often, I hope, with some originality
An Enabling Technology for Power-Constrained Devices
Steve Taranovich  
9/6/2016   Post a comment
Low power is an important feature in portable, battery-operated devices in today’s technologies and as we progress towards such systems in which wearables, 5G smart phones, and energy harvesting become ubiquitous, low power will be an absolute necessity

A Boost for Automotive Start-Stop: Dual Use of EMC Components
Mike Donnelly  
8/30/2016   Post a comment
Automobile manufacturers are increasingly turning to start-stop systems to glean an extra 3% to 12%* of fuel economy out of conventional vehicles. With this approach, the Internal Combustion Engine (ICE) is turned off during idle periods, such as at traffic lights or in stop-and-go traffic, and then automatically restarted when the driver depresses the accelerator pedal

Scott Deuty  
8/22/2016   Post a comment
As LEDs improve in brightness, they are offering many benefits in the automotive world. Having hung on a step ladder in an icy truck lot while changing filament bulbs on over the road trailers in a Siberiacuse winter, I understand the advantages all too well.

Current feedback (CFB) amplifiers have been available since the 1990s, but they are still a small percentage of the overall operational amplifier (op amp) market and may not be covered in basic electrical engineering classes.
We Are Losing our Abilities as Troubleshooters in the Same Way We Are Losing Our Leadership as Innovators
Scott Deuty  
8/16/2016   22 comments
A recent breakdown of a friend’s vehicle made me really start thinking about America’s troubleshooting capabilities. It is a well-known fact that America is losing its leadership as innovators; however, our ability as troubleshooters is in jeopardy as well.

Kristen Villemez  
8/10/2016   7 comments
There are many things which engineers at NASA, Space X, and at a semiconductor company like ADI must consider when developing products for use in space that anyone else wouldn’t have to worry about for earth-bound applications, most notably of which is radiation (of course unless you’re working on a nuclear power plant).
Rarely Asked Questions—Issue 132 Choosing a Precision Op Amp? Trust Goldilocks
Steve Taranovich  
8/9/2016   Post a comment
Choosing the appropriate bandwidth for application of a precision op amp is a lot like the experience of Goldilocks trying to choose between the three bears’ bowls of porridge - one bowl was too hot, one bowl was too cold, and one was just right.

Op Amp Circuitry Ultra-High-Precision Resistor Usage: Matching and Stability Importance
Victor Chertakovsky  
7/26/2016   Post a comment
Some ideal operational amplifier (often op-amp or opamp) configurations assume that the feedback resistors exhibit perfect matching. In practice, resistor nonidealities can affect various circuit parameters such as common mode rejection ratio (CMRR), harmonic distortion, and stability.
