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 3 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? Steve Taranovich 2/4/2015 5 comments 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.
Role Models Ken Coffman 2/4/2015 4 comments Talking about the importance of role models early in our careers.
First Superbowl Ever to be Played Under LED Lighting: A new Era in Lighting Steve Taranovich 1/28/2015 35 comments Unlike the disastrous Superbowl XLVII in 2013, when the Metal Halide stadium lights went out at an inopportune moment, Ephesus LED Sports Lighting, a US-based company that manufactures high-output LED lighting solutions for challenging applications in the industrial and sporting markets, has supplied the Stadium with high performance LED stadium lights.
The Power of the Printed Word Steve Taranovich 1/20/2015 37 comments The MIT Age Lab recently worked with Monotype Imaging in an investigation of effects of typeface on the demand of human-machine interactions during a simulated in-vehicle point-of-interest (POI) menu selection task. Their study showed that people could perform a menu selection task faster and with more accuracy depending upon the text type used as well as white text on a black background vs. the standard block text on a white background. Differences were clearly noted.
Voice, Wireless or Infrared Control? Steve Taranovich 1/20/2015 74 comments One of the key themes throughout my tour of CES 2015 exhibits was the wireless of infrared control of the Smart Home. Using your Smart Phone or Tablet, exhibitors showed how you could easily control many functions in your home.
Latchup and its prevention in CMOS Keith Sabine 1/14/2015 5 comments Early CMOS processes suffered a reliability concern that became known as latchup. It resulted in circuits either malfunctioning or consuming excessive power, and could be either inherent in the design or triggered by voltage spikes on IO pads that could forward bias PN junctions they were connected to.
An AC Current Generator, Part 4 Aubrey Kagan 1/13/2015 3 comments In parts 1 through 3 I described the construction of the transformer we needed to generate the 10Amps AC. We still had to drive the transformer.
Analog circuit bliss can be yours, with a modest investment Analog Angle 1/12/2015 10 comments You can experience the joys and depths of analog circuit design by reading some recent, and not-so-recent, books; they explore topologies, error sources, components, and will likely spark some creative thinking about solutions to real-world circuitry issues.
MIPI Creates the I3C Sensor Interface Steve Taranovich 12/31/2014 13 comments I recently spoke to Ken Foust from Intel regarding his being the chair of the MIPI Sensor Working Group and the important standards work they are doing there. I also had a conversation with Peter Lefkin, the Managing Director of the MIPI Alliance about I3C.
When we last left our heroes, we had narrowed down the application and the goal of our quest to quickly design a power supply using free online design tools. We had also set the stage for this series of blogs where we take a look into the various offerings of power supply design software tools.
