This chapter introduced the most common types of amplifiers in use today: the common emitter BJT, the common source JFET, and the op-amp. At best, this chapter has scratched only the surface of the world of amplifiers. Actually, there are many variations and types of amplifiers. Still, the terminology and design approach you learned here should give you a basic foundation for further study.
Following are the key skills you gained in this chapter:
- How to design a simple amplifier when the bias point and the gain are specified
- How to do the same for an emitter follower
- How to analyze a simple amplifier circuit
