The structure function, and working principle of a transistor 1

A transistor, also known as a transistor, is a semiconductor component used for amplifying current, switching, and signal processing. The main structures of a transistor include a P-type semiconductor, an N-type semiconductor, and an N-type or P-type semiconductor sandwiched in between, known as the emitter, base, and collector, respectively. Below is a detailed analysis of the structure, function, and working principle of a transistor:

1、 The structure of a transistor:

1. Emission pole: It is the pole connected to the external input signal, usually an N-type semiconductor.

2. Base: controls the conduction and cutoff of the transistor, which is the control electrode of CS4236B-KQ transistor, usually a P-type semiconductor.

3. Collector: The output terminal of a transistor, usually an N-type semiconductor.

2、 The function of a transistor:

1. Amplify current: By controlling the base current, the current from the input signal to the output terminal can be amplified, achieving the function of signal amplification.transistor
