The above introduces the negative feedback of a unipolar amplifier, also known as small loop negative feedback.
A transistor, also known as a transistor, is a semiconductor component used for amplifying current
Switch: The transistor can achieve switching function and control whether a circuit is turned on or off.
The transistor is commonly represented by "Q" and a number in circuits, for example, Q17 represents the transistor numbered 17.
The structure of a transistor. It consists of an emitter junction, a collector junction,
The transistor is one of the most common devices in electronic circuits.
