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 ...

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 ...

Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

This audio amplifier circuit delivers up to 200 W of top-class quality for loudspeaker from 4 to 16 ohm. Operating voltage is between 24 and 36 V, max 5 A. The frequency response is from 20 to 20000 ...

The most recent installment of [Dino Segovis’] Hack a Week covers the construction of a simple NPN transistor audio preamp. Some time ago, he built a small audio amplifier using an LM386 which worked ...

Review: The IQ Audio M300 MonoBlock amplifier is deceivingly good, delivering rated power with pristine fidelity and finesse in an efficient, cool running pint sized package. Class D at its best.

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 ...
