Smart Cities: The Future of Urban Areas, Part 2
Paolo Scalisi 9/26/2014 71 comments
Guadalajara is the second biggest city in Mexico, but the biggest city of that country, Mexico City, is moving in the direction of integration of smart energy harvesting technology into the infrastructures of the city.
Ground Is a Cruel Joke
Brandt Braswell 9/19/2014 17 comments
Understanding grounding structures is important to help your circuits to work well and sometimes even to work at all. But ground is not always ground.
Should We Care if AM Radio Fades Out?
Analog Angle 9/19/2014 91 comments
How the cycle has turned: Putting an AM radio into a car was a big advance in the 1920s and 1930s; now, auto vendors are considering eliminating the radio as a standard or even optional feature, due to declining user need and listenership.
Stop Accepting Underperforming Start-Stop Systems
Mike Everett 9/17/2014 2 comments
Today’s energy storage and power delivery systems are not up to the task of start-stop engine cranking. The discerning public will soon demand the technology that is tailor-made for the application: ultracapacitors.
Time-Triggered Ethernet (TTE) Design
Steve Taranovich 9/8/2014 8 comments
The NASA Orion Spacecraft will have a strong fiber optic emphasis for its on-board data network. A Time-Triggered Ethernet distribution network is critical here.
The Power of Light
Matthias Poppel 9/5/2014 25 comments
EnOcean is partnering with the distributor Farnell element14 for a worldwide engineering design competition. Out of more than 200 applicants, 15 finalists were chosen; they are now challenged to develop an innovative monitoring and automation application.
Power Dissipation: My Arch-Nemesis
Aubrey Kagan 9/3/2014 15 comments
Experience should have taught Aubrey Kagan to consider power dissipation before introducing a component into a design. Unfortunately, it always seems to come back to bite him.
EMI Noise, Part 1: Don’t Be the Problem
Edgardo Menendez 9/3/2014 7 comments
Electromagnetic interference (EMI) is a problem in all electrical and electronic circuitry. This six-part series will discuss the available component solutions for mitigating EMI noise emissions and how to make your circuitry less susceptible to EMI.
This article explains how the latest-generation SiC FETs are ideally suited to new inverter designs with lower losses than IGBTs and proven robustness against short circuits, even at high temperatures and under repetitive stress
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.
