First Superbowl Ever to be Played Under LED Lighting: A new Era in Lighting Steve Taranovich 1/28/2015 30 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 36 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 71 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 4 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.
The Big Lie About LEDs Scott Elder 12/22/2014 51 comments The world has been told that LEDs are the future, in part because they are economically the right form of long-term lighting and there are environmental benefits as a great aside. Well, maybe the environmental argument is true, but the economical one is not.
Analog Devices Design Tools: VisualAnalog Jonathan Harris 12/19/2014 4 comments We begin this series of blogs by taking a look at ADIsimADC, which is a quite relevant design tool for Jonathan Harris, an applications engineer in ADI's high-speed ADC group.
Whatís Driving Interest for Supercapacitors? Steve Taranovich 12/16/2014 88 comments Chances are youíve heard mention of supercapacitors if you havenít yet implemented them in a system design. Thatís because when components experience a 30% compound annual growth rate, it is usually driven by game-changing advantages.
An AC Current Generator, Part 2 Aubrey Kagan 12/11/2014 3 comments When testing, a 10 amp AC current is fed into the module being tested (DUT) and the current is measured across a 25 mΩ shunt internal to the DUT.
EDA Tools Should Be Free Scott Elder 12/4/2014 5 comments The evolution of technology is being hindered by the lack of high-end tool access. Most innovation originates from small organizations with little or no money to pursue their visions.
An AC Current Generator, Part 1 Aubrey Kagan 12/1/2014 9 comments I wrote an article on this topic in 2000 that was published on Circuit Cellar Online. I believe that the basic information that I wrote about is still relevant and so I am rewriting the article as a blog.
Bosch Sensortec at Munich Electronica 2014 Divya Thukkaram 11/26/2014 30 comments When I was having a chat with one of my colleagues with whom we shared the booth at Electronica, I saw a young gentleman with a companion moving our demonstration board frantically, checking the connector cable erratically to see an animated blue shark moving in synchronous with the board.
