Measuring an Alien World
Steve Taranovich 7/30/2014 17 comments
How do you measure and analyze a planet one-and-a-half times the size of Earth and 300 light years away? How can we know its composition? With the incredible technology of a cryogenic telescope like the Spitzer and Kepler Space Telescopes.
Sensor Footprint Evolution: Does Size Matter?
Steve Barraclough 7/25/2014 10 comments
Industry observers will not argue that the explosion in the adoption of motion sensors, principally accelerometers, was enabled by reducing the form factor to the point where the sensors could easily be integrated into mobile applications.

Here is the third of three short tech nuggets, by Rich Nowakowski from TI, before our “Ask the Experts” session on Wednesday, July 23, at 1:00 p.m. ET (10:00 a.m. PT).
How a Coffee Packaging Machine Educated Me
Aubrey Kagan 7/18/2014 29 comments
One of my first projects was to design a control for a coffee packaging machine. It was in the late 70s and microprocessors were on everybody's lips, but few actually knew anything about them.
Energy Harvesting for Wearables
Thomas Kail 7/15/2014 23 comments
Wearable applications including smart watches, sport watches, fitness bands and more are growing in popularity, and so, too, is the demand for intelligent sensors to use in them. If analyst predictions are correct, the market is going nowhere but up in the coming years.
Improving Analog Design Time
Keith Sabine 7/9/2014 10 comments
Designers can estimate parasitics early in the design flow, at the RTL level, to see if they meet timing and power criteria. Thus design changes can be iterated relatively quickly until the design goals are met, with detailed layout following.
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.
