A current of electrons passing through a potential barrier follows a Poisson process that is characterized by white noise. This so-called shot noise originates from the quantization of the electric ...

Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...

Feedback field-effect transistors (FBFETs) represent a significant evolution in semiconductor device technology. Incorporating a positive feedback mechanism, these devices exhibit extremely steep ...

The recent EDN article of Bruce Trump () on the input impedance of an op-amp circuit took into account the single-pole roll-off of its loop gain. He showed with a simple derivation how the equivalent ...

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 ...
