Switch: differences between transistor circuit co-set, co-base, and co-shooting

A common set, a common basis, or a common shot refers to a circuit, which is the connection state of a transistor circuit rather than a transistor. The so-called "Total" refers to the total part of the input and output circuits. It is determined by the AC equivalent circuit.
Common collector circuit-the collector grounding of the transistor. the Collector is the public pole of the input and output;
Co-base pole circuit-the base pole grounding of the transistor, the base pole is the public pole of input and output;
Co-launch pole circuit-the ground of the transistor emitter pole, which is the public pole of input and output.

 

Another faster resolution method is to remove the signal input and obtain the signal from the other side to the other side. Or, in the AC equivalent circuit, the pole that is grounded is the pole in total. (A total of XX circuit is to set the signal (or potential) reference point at XX, which is also the common reference point of AC and DC .) --------------------------------------- The main characteristics of the table is as follows: Example diagram: Figure 1 common circuit (common_emitter) diagram Diagram 2 common circuit (common_collector) diagram 3 common circuit (common_base)
