India’s Potential Silicon Valley in the “Land of the Coconut”: Kerala
Steve Taranovich 2/25/2015 6 comments
There are 150 engineering schools in the state of Kerala with graduates leaving India for the allure of companies elsewhere in the world. The state of Kerala wants to keep these engineers right there in this region where they have graduated and is trying to create a “Silicon Valley” in India.
The Future of Custom ASICs
Steve Taranovich 2/25/2015 3 comments
For decades, electronics product innovation has been incremental in nature, relying largely on the next generation of semiconductors to deliver performance improvement. For almost 50 years Moore’s Law has delivered 2x performance (power or cost) improvement in semiconductors every 18 months, outpacing any product or system level innovation cycle that could be achieved by even the most ambitious hardware teams. What has evolved is a “sit & wait” approach, to product innovation. However it is now clear that Moore’s law is broken, and the implications are profound for hardware designers.
You Need a Power Supply Designed by When?
Scott Deuty 2/25/2015 Post a comment
You’re in a small company that needs to turn a product quick. Nobody in the company has any power supply design experience yet you need to drive LEDs from a universal (US and European) wall input voltage. What do you do?
A snow-thrower on steroids
Luca Difalco 2/19/2015 7 comments
With the US East Coast digging out from yet another snowstorm in a year-long march of wintry weather, even the most stalwart residents are suffering from snow overdose, leading them to wonder: WHERE ARE OUR SNO-BOTS?
Time of Flight
Steve Taranovich 2/18/2015 6 comments
The phrase “Time of Flight” has come up quite a few times in recent weeks. I think it is important to understand what this relates to and more importantly, what it relates to in today’s latest electronics developments.
Forget about 10 GHz—let’s aim for 100+ GHz
Analog Angle 2/10/2015 5 comments
Now systems are moving higher, with activity in the 5 GHz Wi-Fi band as well, due to crowding and interference issues at 2.4 GHz. Ironically, this at least partially due to the success of the cellular, Wi-Fi ad ISM initiatives at 2.4 GHz.
Delta-sigma ADC basics: How the digital filter works
Precision Hub 2/10/2015 4 comments
Designing with a delta-sigma analog-to-digital converter can help achieve the highest possible resolution in your system. But to maximize this architecture’s benefits, it helps to understand how the delta-sigma modulator and digital filter in the ADC combine to achieve greater measurement resolution.
Calculator or Slide Rule?

In February 1972, the first relatively affordable and hand-held electronic calculator was made available, for scientists only, priced at $395. Hewlett Packard's HP-35 was the first handheld calculator to perform advanced mathematical functions.

Talking about the importance of role models early in our careers.
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.
