Operational amplifiers (op amps) have proliferated from specialized instruments made from large tubes to tiny monolithic circuits composed of a sliver of silicon, germanium or gallium arsenide. Dozens ...

WiiM has been throwing rocks into the affordable hi-fi pond for a few years now, and has been successful enough to make us, ...

From the theoretical development in the previous article (Reference 1), basic application circuits can be realized. The gain equations show that the inverting stage may have a closed loop gain (Acl) ...

I've got a pair of standard non-powered speakers. I'd like them to play whatever Chromecast Audio is playing. I assume/understand I'll need to buy an amp. Here's my question though...do I really need ...

How a paper substrate and biodegradable circuitry can be used for basic circuits. How the researchers fabricated and connected active and passive devices literally “on paper.” Details of their first, ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

Using a paper substrate and wax resist, plus conductive and non-conductive inks, researchers have developed a functional, biodegradable circuit and its carrier. How a paper substrate and biodegradable ...
