Fully-Differential Amplifiers and the Leading Edge in Electronics
Dennis Feucht 9/7/2018 2 comments
Semiconductor companies have now had fully-differential amplifiers in their product lines for a few years, though these amplifiers have been in leading-edge electronics for decades. These diff-amps are differential not only at their input but also at their output, doubling output range.

This is a throw-together project using junk box parts that can be useful whenever an interesting-looking waveform is needed for a demonstration or for the beginnings of a video test generator or curve tracer.
Alternative Uses of Packaging in Electronics

In an era of collapsing economies, waning affluence, and too much garbage amid scarcity, a characteristic that is part of the engineering character - resourcefulness - is due to come back in vogue, as we are challenged to optimize the use of limited resources.
The Shape of Electronics Expertise
Dennis Feucht 9/11/2017 2 comments
As we progress in our acquisition of electronics skills, we occasionally reflect on the “shape” that our knowledge and skills are taking. This article is an overview of basic decisions that “sculpt” our know-how and some of the consequences of the shape of it.
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.
