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.

So far we’ve taken a look at the basics of transistor biasing through the common emitter amplifier, then introduced a less common configuration, the common base amplifier.

The common-base configuration is so little used, it doesn’t even register on many engineers’ radar. So, as a self-professed analog guy , I’m embarrassed ...
