A common way to get more gain out of transistor circuits is to cascade similar amplifiers. It is, of course, still possible to use negative feedback on single transistor amplifiers, But, first, let’s design a simple Common Emitter amplifier. One Transistor Amplifier We will use the very common general purpose 2N3904 NPN transistor.

The common emitter or source amplifier may be viewed as a transconductance amplifier (i.e. voltage in, current out) or as a voltage amplifier (voltage in, voltage out).As a transconductance amplifier, the small signal input voltage, v be for a BJT or v gs for a FET, times the device transconductance g m, modulates the amount of current flowing through the transistor, i c or i d.

Negative feedback, collector feedback, decreases the output signal. The resistances of R1, R2, R3, and Rfeedback function together as a signal-mixing network so that the voltage seen at the base of the transistor (with respect to ground) is a weighted average of the input voltage and the feedback voltage, resulting in a signal of reduced amplitude going into the transistor.
