In Seemingly Simple Circuits: Transresistance Amplifier, Part 1– Approximating Op-Amps, the op-amp was approximated from a single-pole, finite gain amplifier to an infinite-gain, single-pole op-amp, ...

The debate still goes on as to which are better, valves or transistors. We don’t intend to get involved in that argument here. But if you can’t make your mind up, you should try out this simple ...

In a signal-conditioning op-amp application, is there an optimum circuit topology for optimizing SNR and SFDR? Here’s a succinct analysis, part mathematical, part simulation, and part cookbook, from ...

Build a mini amplifier using simple electronic components. A practical DIY electronics project perfect for beginners, students, or hobbyists who love sound experiments. #MiniAmplifierDIY #ElectronicsD ...

One of my first jobs as a freshly minted graduate engineer involved the maintenance of a set of analogue chart recorders. They were museum pieces by the early 1990s: a motorized roll of graph paper ...

I've noticed that my 2 year old daughter has an unhealthy interest in my current, old Denon amplifier from the beforetime that has lots of buttons and lights. I've also noticed that my audio input ...

Amplifying the human voice presents some tough challenges. One of the toughest of these is providing enough amplification to make sure a soft-spoken person can be heard while allowing sufficient ...

Add articles to your saved list and come back to them any time. A $25 USB stick holds more data than 23,000 3.5-inch floppy discs; maybe you knew that. Mobile phones have more computing power than the ...
