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

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.
The ever-increasing use of wireless devices, such as mobile phones, computing, and remote sensing systems, have led to increased demand and dependence on the use of batteries.
A three-part series of articles explains how to minimize interference through proper PCB design and layout.
In such things as laboratory power supplies or electronic systems, in which various components are connected to longer cables, the regulated voltage is not always particularly accurate at the point where it is needed due to various voltage drops across the interconnection lines.
There area plethora of USB Type-C articles out there, but this is the first one I have seen with a really neat design architecture to shrink the board footprint with a high level of integration.
The required selectivity of a customer design implied four-pole filters with about 10% bandwidth (passband width about 10% of the centre frequency). There was a catch---a tight power budget
