One of the Doomsday scenarios that continues to fascinate is the possibility of the nation's electric grid being laid low by an electromagnetic pulse (EMP) or other attack

We now get to the heart of the isopot circuits: the multipliers.
The Drone Dilemma, Part 2: Legal
Scott Deuty  
1/26/2016   2 comments
There is no doubt that legal subjects intermix with privacy and air space. So the legal subject matter that is referred to herein will focus on drone registration and the development of laws and regulation. Other legal matters such as privacy and air space will be covered separately.

The following isolated anapot, or isopot, design is intended as a design “template” for general application wherever a manually-actuated pot is to be replaced and actuated by an analog voltage.
Beware the unintended consequences of more-efficient design

Sometimes the urge to do good at almost any cost has real-world implications that we didn’t think about or worse, don’t care to know about.

This article introduces the MIPI Alliance Gigabit Debug portfolio of specifications that maximizes the utility and efficiency of debug tools.
Build a high-voltage linear regulator

1/12/2016   13 comments
Generating a regulated voltage from input rails exceeding 100 V is challenging. A limited selection of integrated solutions complicates the problem. Creating a discrete voltage regulator enables a low-cost solution, but the design process is involved and requires a deeper understanding of key engineering tradeoffs, with an emphasis on device thermal properties.
Op amp basics: Small signal bandwidth and overall performance
Signal Chain Basics

One of my favorite parts of the annual Analog Aficionados dinners is the informal show-and-tell among designers.
“O CMRR, CMRR! Wherefore art thou CMRR?”

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.
