Transistors with Negative Feedback
H. E. Kaden · 1965
Negative feedback is a means much used with the tube to influence and stabilise the amplifying properties of an amplifier. Even greater use is made of these methods with transistors because the transistor is extremely subject to external influences ; its dependence on temperature is an example. With negative feedback, as the name implies, part of the amplified a.c. voltage α • v 2 is allowed to operate against the applied input voltage v 1 . In principle, therefore, we can distinguish between a series and a parallel coupling.
