An amplifier is a circuit which boost the input signal amplitude to a level that is much much better than the input signal. Single transistor amplifier circuit are very low power consuming device which boost the input signal to a specific level.
The amplifier are classified in to classes such as Class A ,Class B ,Class AB,Class C and Class D .In this project we will discuss about the class A amplifier and its application. This type of amplifier can build easily but the quality of this circuit is not very good . Due to less consuming of power this amplifier circuit can run with a single battery many hours .
The single Transistor amplifier are also known as common Emitter amplifier and its is widely used die to its simple circuit design and less power consuming.
Amplifier circuit Components
1-Speaker 3W 4 Ohms
2-Capacitor 10uF 16 V
3-Resistor 4.7 K
4-Transistor NPN type
The amplifier circuit are use to boost the input signal to a level that is much better than the input signal.
