Presenting the Common Emitter Amplifier In the next three tutorials, including this one, we will present the three elementary topologies of bipolar transistors based amplifiers : the Common Emitter Amplifier, the Common Collector Amplifier and finally, the Common Base Amplifier. We...

Presenting the Common Base Amplifier In this article, we present the last topology of amplifiers for bipolar transistors known as the Common Base Amplifier (CBA). In Figure 1 below, the electric diagram of a CBA is presented, no particular bias circuit or decoupling capacitors are shown...

Presenting the Common Collector Amplifier This article deals with another type of bipolar transistor architecture used to amplify signals that is commonly known as Common Collector Amplifier (CCA). The CCA can also sometimes be called emitter-follower amplifier and we will understand...
