As we’ve followed a trail through Hi-Fi and audio systems from the listener’s ear towards the music source, we’ve reached the amplifier. In our previous article we gave a first in… ...

A 1 kΩ collector resistor and a 330 kΩ base resistor has never failed me for a small-signal self-biasing audio amplifier, ... as well as something of a homage to the single transistor amplifier.

Single-transistor graphene amplifier. Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better ...

ThermalTrak integrates power output transistors with thermal bias diode. One of the major design concerns in the output section of a typical class AB audio amplifier is output bias and stability over ...

Graphene has been used to create a triple-mode, single-transistor amplifier that could potentially replace many traditional transistors in a typical integrated circuit.

Millions of guitar player can’t be wrong. Well over 80% of guitar amplifiers new and existing still use vacuum tubes. Based on my experience, that could really be over 90%. Nevertheless ...
