When the amplifier circuit is amplifying the signal, it always has two electrodes to be used as the input port of the signal, and there are two electrodes to be used as the output port. There are three kinds of circuit according to the connection mode between the three electrodes of the semiconductor transistor and the input & output terminals: the common emitter circuit, the common base circuit and the common collector circuit. The connection modes of these circuits are as shown in figure. Figure 1 The three connection modes of the semiconductor transistor basic amplifier circuit
