Video Name:
The Common Emitter Amplifier [Transistor TS 4]
Video Description:
Transistor tutorial series episode 4. In this episode we introduce the common emitter transistor amplifier circuit, go over its biasing and small signal model
then conclude with a step-by-step design and demonstration of the common emitter amplifier in the lab
Concepts discussed:
- common emitter transistor amplifier overview
- simple biasing circuit for common emitter amplifier
- low frequency small signal analysis
- step-by-step design of a common emitter amplifier of a desired gain
- demonstration of that circuit in the lab
- changing the gain of that circuit and demonstrating the differences
- explore what happens when the signals become too large
