Control theory is a vital and standard part of engineering studies: the effectiveness of negative feedback to keep jet-fighters airborne, ferries afloat and nuclear power plants a-non-exploding has ...

Feedback is an ubiquitous and unavoidable basic technique that keeps the world running. It is only controversial in consumer audio, and then only specifically in power amplifiers. This dates from ...

Emitter/source degeneration is a technique used to guard against drift in transistor parameters like beta. In addition, it helps linearize the small signal output. The transfer characteristic of a BJT ...
