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 ...

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 ...

This headphone amplifier provides a gain of less than 10 by a single stage common emitter amplifier and then via a direct coupled emitter follower configuration per each channel. As it seen from the ...

This application note discusses the Avago Technologies AT-32063 dual low noise silicon bipolar transistor. The AT-32063 consists of two AT-320XX transistors mounted in a single package with all ...

Sometimes I wish FETs had become practical before bipolar transistors. A FET is a lot more like a tube and amplifies voltages. Bipolar transistors amplify current and that makes them a bit harder to ...
