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 ...

I remember browsing in the engineering library when I was a student and coming across books devoted entirely to amplifiers. Surely amplifiers play an important role in electronics. There are plenty of ...

Maintaining perfect stability through negative feedback is a basic element of electrical circuitry, but it’s been a mystery how cells could do it — until now. Mustafa Khammash’s small Lego robot is ...
