Space Mission Lifetimes

Designs for space applications are commonly created with mission life expectations reaching 15 to 20 years and even longer in some cases
Current Shunt Resistor Inductance: It Matters
Jerry Steele 8/16/2018 3 comments
In high frequency switched systems where you measure current with a shunt, you may observe problems such as excessive amplitude on sine wave current ripple, overshoots on square wave ripple or any rapid transition of current, or excessive high-frequency noise. These problems are due to current shunt inductance, which becomes more significant at lower values of shunt resistors
Designing LiDAR and more into Autonomous E racing

I think that ROBORACE is one of the most intriguing Motorsports I have ever seen for advancing the technology necessary for safe and practical electric vehicles. Its uniqueness is in the fact that their race cars are driverless as well as being electric.
Extracting Loop Gain and Phase Information from Simulation
Michael Steffes 8/9/2018 7 comments
Modern high-speed op amps and Fully Differential Amplifiers (FDAs) push the limits in every direction to deliver the best harmonic distortion at the lowest quiescent power. This often leads to relatively low phase margin designs in what would normally appear to be benign application circuits.
Silicon Carbide Leads the Wide Band-Gap Revolution
Dr. Zhongda Li 8/6/2018 Post a comment
Wide band-gap semiconductors such as GaN and SiC offer significant advantages over conventional silicon devices, for performance-critical power-conversion applications. Cost-effective, proven SiC products are on the market now, and ready to drop in as a straightforward upgrade
Yes, Do Put Your Label on Me

Simple things like proper labeling of cables and additional annotation is an easy way to make a big difference in debugging of prototypes and pilot units.
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.
