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 ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...

Immediately, I learned that the common base configuration gain was 6db lower than the common emitter. This blew my mind. Then I started checking input resistance and was shocked at how low it measured ...

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 ...

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 ...
