It’s that time of year where students return to school and to be honest, I’m still miffed at the costs associated with college
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

Quiz questions published in EDN in 1985 and 1986 are still relevant today. Jim may be gone, but the analog gremlins live on.
Measuring LDO Noise Spectral Density for a Novice

Characterize the noise spectral density (NSD) of an LDO, otherwise known as a low dropout voltage regulator.
Short notes about lightning, Part 2: Electrostatic field strength measurement
Victor Lorenzo  
8/24/2016   Post a comment
Lightning protection strategies gain a safety boost when complemented with storm tracking and prediction. There existing relation between the formation of electrostatically charged clouds and the occurrence of lightning can be used for improving safety and thunderstorms prediction accuracy.

How to stop a train – capture energy, save money
Shaw Lynds  
8/22/2016   1 comment
Approximately 80 percent of total energy consumed by trains is for traction, and this energy is generally given off as waste heat as the train decelerates into a station.
Resistor orientation and the thermal EMF effect

Maintaining a constant temperature around precision resistors is integral to maintaining the stability of a circuit
LEDs Are Becoming the Prominent Automotive Lighting Technology
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.
Signal Chain Basics #115: The impact of the feedback resistance value on gain, bandwidth, and slew rate in current feedback amplifiers
Signal Chain Basics  
8/18/2016   7 comments
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.
Going Full Tilt
Ian Beavers

Adding wireless connectivity and an app to a basic product brings benefits, but at what design cost plus potential user headaches?
Seemingly Simple Circuits: The TL431 Voltage Regulator, Part 2
Dennis Feucht  
8/12/2016   Post a comment
We submerge somewhat deeper into analysis of the seemingly simple TL431 voltage reference with transconductance amplifier to find that some useful design parameters are missing from the manufacturer specifications.
Jupiter: The IC Danger Zone, Part 1
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.

Ultraviolet rays are not always dangerous, they are useful to the human body to produce vitamin D, however it is very important to avoid excess of exposure because many dangerous diseases might occur; for example, the human eye in case of excessive exposition time to the UVs
SEMICON West 2016: My top 5 most interesting discoveries about Sandia Labs and 5 incredible facts about Keahi Seymour’s “Bionic Boot”

Being at SEMICON West 2016 in San Francisco this year for the first time, I saw so many new aspects of the supply chain that I had never looked into or, in some cases, was not even aware of. I would like to share with you 5 most interesting discoveries each about Sandia Labs and the Bionic Boot exhibits that I saw at this event
