The common emitter amplifier that we saw last time is an inverting amplifier, in that as an increasing current on the base causes more collector current to flow it pulls the collector voltage down.

Now, in part – III we will cover the some more important concepts like Junction Transistor, Common-Base Configuration, Common-Emitter Configuration Common-Collector Configuration.

There is a third transistor amplifier configuration, as you might expect for a device that has three terminals: the so-called Common Collector amplifier.
