The classification of the amplifier is based on the device terminal which is common to both input and output circuit. In the Bipolar Junction Transistor, there are three classes namely. a common emitter, common base, and common collector.

What are the different method of classification of amplifier?
Amplifier Class by Conduction Angle
| Amplifier Class | Description | Conduction Angle |
|---|---|---|
| Class-A | Full cycle 360o of Conduction | θ = 2π |
| Class-B | Half cycle 180o of Conduction | θ = π |
| Class-AB | Slightly more than 180o of conduction | π < θ < 2π |
| Class-C | Slightly less than 180o of conduction | θ < π |
On what basis amplifiers are classified?
Power amplifier circuits (output stages) are classified as A, B, AB and C for linear designs—and class D and E for switching designs. The classes are based on the proportion of each input cycle (conduction angle) during which an amplifying device passes current.
What does the classification of an amplifier depend upon?
The classification of an amplifier depends upon the size of the signal, large or small, its physical configuration and how it processes the input signal, that is the relationship between input signal and current flowing in the load.
What are the different types of amplifiers?
different types of amplifiers are also often described in system or block diagrams by name.
- Amplifier.
- Audio Frequency Amplifier.
- Intermediate Frequency Amplifier.
- R.F. Amplifier.
- Ultrasonic Amplifier.
- Operational Amplifier.
