A large part of our industry's momentum is fueled by predictions about the next big thing, but these often fail the harsher reality test
Low Power Switched Cap Bandgap
Scott McLeod 12/13/2015 1 comment
Whether designing a bandgap reference for medical implants, monolithic battery charging or just trying to minimize operating power, a switched capacitor bandgap implementation fits the bill nicely. With a switched cap circuit, the creation of a bandgap voltage is based upon charge transfer as opposed to constantly biased circuitry and thus lends itself well to low power operation.
Missing Half the Power

When using an ADC’s internal digital down conversion (DDC) processing for decimation, my single tone real input signal is losing 6dB of power. What is happening?
What’s new in Remote Control Technology?
Sean Donnelly 12/6/2015 Post a comment
Infrared, IR, Communications technology is used to link consumer equipment such as a remote control with a television since the late 1970’s. Over the years manufacturers have developed a multitude of digital communication protocols most commonly based on Amplitude Shift Keying, ASK, modulation. The introduction of new protocols differentiated communication schemes, im-proved robustness, and optimized data transmission capability
EHS – A Disease For The Wireless Age?
Paul Pickering 12/1/2015 3 comments
Is electromagnetic hypersensitivity (EHS), characterized by sensitivity to non-ionizing electromagnetic fields at levels well below those permitted by international radiation standards, actually just the "nocebo" disease du jour or does it have a basis in science?
Analog, US to Lead Chip Market Growth

The global semiconductor will be flat in 2015 at $336 billion, up 0.2 percent from 2014, according to the European Semiconductor Industry Association referring to figures from the World Semiconductor Trade Statistics (WSTS) organization.
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.
