Electronics Tutorial about the Common Emitter Amplifier and Transistor Amplifier Circuits including its Load Line Graph and Calculations

This project utilizes the connection between common base and common emitter circuits. The transistor Q1 is connected as a common base amplifier and has a low input impedance and high output one. Q2 is emitter follower with high input and a low output impedance. Both circuits have a 0 deg phase shift, so no Miller effect is present. All these, make the pair easy to couple and with high frequency range.
