Wireless communication enabling technologies are under constant evolution, especially in terms of power consumption efficiency and security. But not always the most dangerous security breaches come from the underlying security platform.
800 Pound Gorilla, Part 2: Letni

If you are in power electronics, you may have been the tail wagged by the dog Letni. In order to power microprocessors, the Voltage Regulator Module specifications were created.
IMS2016: Day 2 Review
Jonathan Harris 5/26/2016 Post a comment
. The day started off just a little slower than yesterday but quickly picked up pace and resulted in another day of steady booth and floor traffic. I had some great questions about the products we are displaying in my demonstration as well as many questions on our other technology on display at the IMS show.
IMS2016: Day 1 Review
Jonathan Harris 5/25/2016 Post a comment
I hope that you had a chance to visit the IMS2016 show during the first day. There was a noticeable increase in floor and booth traffic compared to the show last year. Perhaps you all read my preview blog this week and decided to come and check out our great demonstrations at the Analog Devices booth!

The self-healing circuitry of science fiction isn't here yet, but there's significant research underway at NASA and universities to make it into a reality
The Bootstrapped Astable Multivibrator
Dennis Feucht 5/17/2016 12 comments
Some time ago, I reverse-engineered a low-cost inverter made by Vector Mfg. (now Black & Decker). It uses a classic 2-BJT astable multivibrator (AMV) but with a circuit design twist, as shown below. What is the purpose of R6?
Non-correlation of Peak Noise and Peak Current
Raj Nair 5/16/2016 2 comments
Is a power grid represented with good accuracy as a complicated mesh of resistances? We answer the first part of this exploration – the non-correlation of peak noise with peak current – in this experimental study.
Finding the sweet spot for hybridization
Shaw Lynds 5/11/2016 1 comment
Using the Zakeri model, Maxwell Technologies depicts the lifecycle cost savings of using a hybrid energy storage system, featuring both ultracapacitors and batteries, for grid applications.
Who ate my dBs?
Steve Taranovich 5/9/2016 Post a comment
I am setting my signal generator to output a CW tone at a certain power, which per my math, should give a -1dBFS signal at the ADC. However, I am seeing -15dBFS! Who ate all of my dBs?
Removing the vuvuzela narrow-band noise was presenting challenges to broadcast engineers
This article discusses how using a single synchronous buck controller can output the most common voltage rails, and accommodate a wide range of operating input voltages from 3V to 40V, and at a reasonable BOM cost.
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.
