2-29 Now that we have analyzed the basic transistor amplifier in terms of bias, class of operation, and circuit configuration, let's apply what has been covered to figure 2-12. A reproduction of figure 2-12 is shown below for your convenience. This illustration is not just the basic transistor amplifier shown earlier in figure 2-12 but a class A amplifier configured as a common emitter using fixed bias. From this, you should be able to conclude the following:   Because of its fixed bias, the amplifier is thermally unstable.   Because of its class A operation, the amplifier has low efficiency but good fidelity.   Because it is configured as a common emitter, the amplifier has good voltage, current, and power gain. In conclusion, the type of bias, class of operation, and circuit configuration are all clues to the function and possible application of the amplifier. Q26.
