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 ...

Just as the common emitter amplifier and common base amplifier each tied those respective transistor terminals to a fixed potential and used the other two terminals as amplifier input and output, so ...

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 ...

An engineer asked me for help when he encountered what appeared to be strange phenomenon while testing a prototype circuit in the system. He saw “mysterious” clipping distortion of the signal at the ...

In an earlier blog (Comparing Op-Amp & Video Amp Topologies, Part 1), we examined the bandwidth and phase requirements for processing video. In the most recent blog, we looked at the AC and DC ...
