Power amplifiers topic to cover the classes of amplifier

An amplifier is an electronic device or circuit. Amplifiers are used to increase the magnitude of the signals, electric power to its input as voltage, and current. An amplifier is a generic device that works according to the configurations in a circuit and the designed modes of operation in the circuit structure.

Amplifiers are with the different types of amplifier classes used in wireless communications and broadcasting as small signal amplifiers, large signal, and power amplifiers. Week signal amplifier type will often be used in the wireless device.

classifications of the amplifier

What are the classifications is available in an amplifier?

Amplifier classes are classified by the different forms of electronic circuits. The divisions in the amplifier are ranges from Operational amplifier, small signal to large signal amplifier and up to power amplifiers that are depend upon the Signal Strength.

The physical configuration of the amplifier will process the input signal and it relates with the current load flowing in the system. The configuration design in the amplifier will first meet the signal size whether it is large or small among the different classes of amplifiers.

What are the different classifications of amplifiers and how they work?

Not all the amplifiers are the same in their output and diagnostic, the classifications of the amplifier will be classified based upon each performance amount of output signal and characteristic in the configured style.

There are different types of amplifiers classes are named in letters like A, B, C, AB, E, F, T and etc.,

  • A class A amplifier – is a device that uses complete input signal and remains active with high linearity. Works even on low signal and provides better peak frequency and long circuit stability.
  • Class B amplifier – there are two active devices is available to conduct half of the actual cycle amplification from the input. It Provides low heat sink space and there is a profound limitation to crossover distortion.
  • Class AB amplifier – alternate approach to conduct both class A and B to overcome the cross-over distortion. The efficiency range will get differs in Class A and class B.
  • Class C amplifier – the additional option of untuned mode offers to omitted the tune section and it gives a huge distortion than the than amplifiers across the output. The tuned section and its operation in the amplifier are named as clamper.
  • Class D Amplifier – it is not works as a regular amplifier; it works in the method of switching amplifier and conducts the direct input signal to transfer as a variable pulse width in the modulation.
