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 ...

This single transistor audio mixer is used in an amplifier circuit design with base driven transistor and with its emitter being current controlled, most of the driving current flows through the ...

Usually targeted at audio applications, these circuit blocks find homes in all types of designs. Here’s a quick study of their operation and properties. Two of the most often used amplifier building ...

If you open up the perennial favourite electronics textbook The Art Of Electronics and turn to the section on transistors, you will see a little cartoon. A transistor is shown as a room in which ...

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 ...
