Did you ever wonder how to calculate the stability of an op amp circuit? Put the wrong compensation network into the feedback loop, and you’re got an attenuator or, worse, an oscillator. It’s not ...

JFETs are, almost invariably, depletion mode devices, which means that there will be some drain current at a zero-applied gate-source potential. This current will decrease in a fairly linear manner as ...

If you already know about class A, B, and AB, they are all linear amplifiers with constant gain where the audio is fed to the base of a transistor. The latest class D audio amplifier is switch type ...
