Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

There is so much to learn about the single-transistor amplifier, that this brief tutorial hardly scratches the surface. This discussion considers only the common-emitter configuration as applied to ...

Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better than conventional amplifiers thanks to ...

Reading an article about the first transistorized Hi-Fi amplifier, [Netzener] got the itch to make one. But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit.

Fig 1. This basic source-follower circuit is the kind of amplifier you would find in an electric bass guitar amplifier. R6 provides the feedback. On the other hand, low-distortion applications require ...

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

IN THE AGE OFwireless speakers and Bluetooth streaming, vacuum-tube amplifiers may seem antiquated, but you don’t have to be an audio nerd to appreciate their appeal. Designed to power traditional ...
