Voltage negative feedback
The voltage negative feedback is a circuit concept in the area of basic transistor circuits . It is used to stabilize such circuits with regard to their operating point.
The voltage negative feedback reduces the voltage gain in the emitter circuit and its associated input resistance. Furthermore, the negative voltage feedback reduces signal distortions, because the influence of the transistor sizes and thus also their non-linearities and scatter is reduced.
In addition to voltage negative feedback, current negative feedback is used.
