A FET is a voltage amplifier rather than a current amplifier, its input impedance is many orders higher than that of a bipolar transistor, and thus you will find FETs used in many applications ...

Single transistor holds the potential to power a high-performance amplifier with the right components and setup. By following precise techniques, this transformation enhances audio output, delivering ...

When a positive voltage is applied to the base ... These circuits will allow you to observe the operation of a transistor as an amplifier, just as Walter Brattain did at Bell Labs in the winter ...

and two for the audio power amplifier, but it’s possible we’re not factoring in the relatively low gain of a 1950s transistor and they’d need that extra part. In the cut-throat world of late ...

In order to develop the necessary technology, the project Magellan—High Efficiency mm-Wave GaN Transistor High Power ...

Opinions expressed by Forbes Contributors are their own. Technology journalist specializing in audio, computing and Apple Macs. Probably one of the most celebrated amplifiers ever made—the 33/ ...

The first transistor was about half ... itself sat on a metal plate attached to a voltage source. This contraption was the very first semiconductor amplifier, because when a bit of current came ...

Here comes a new compact power amplifier that isn’t made in China: Pro-Ject Audio Systems’ Amp Box RS2 is made in Europe; it ...
