What is the meaning of the Amplifier Classes

What are the Amplifier Classes?

The Amplifier Classes are the term used to differentiate between the different amplifier types, which represent the amount of the output signal.

What is the meaning of the Amplifier Classes ?

Amplifier classes are mainly lumped into two basic groups. The most commonly constructed amplifier classes are those that are used as audio amplifiers.

Class A

Class A, literally means “the best class” of amplifier . The class A amplifier has the highest linearity over the other amplifier classes .

Class B

Class B amplifiers were invented as a solution to the efficiency and heating problems associated with the previous class A amplifier. The efficiency of Class B amplifiers is much higher than thatof the class A amplifier.

Class AB

the Class AB Amplifier is a combination of the “Class A” and the “Class B”.

the class AB amplifier is a good compromise between class A and class B in terms of efficiency and linearity.

Class C

class C amplifiers are commonly used in high frequency sine wave oscillators and certain types of rf amplifier.
