Hello,and welcome back to Enghme for a new electronics project.Single-transistor amplifier circuits can generally understand basic amplifiers and their different configurations. This circuit is easier to make, but more difficult to understand. Because the single-transistor amplifier can be made into three different configurations, common base, common collector and the most widely used common emitter. Since co-transmitter is very popular, in this article, we will build a co-transmitter configuration.
Hardware Components:
1-Capacitor
2-Resistor
3-Transistor
4-Battery 4V
5-Speaker

Description of Single Transistor Amplifier Circuit:
This single-transistor amplifier circuit is very simple to manufacture. It uses a simple BC547 transistor. The 2.2K resistor is the base resistor of the transistor. The audio signal is provided at the base of the transistor, allowing current to flow between the collector and emitter. The capacitor wiring in this circuit isolates the base of the transistor from the input source. Now the basic current or voltage will not affect the input audio. When the input audio is provided at the base of the transistor, it enters the front stage. It produces the maximum amplitude at the output during the entire audio cycle provided to the transistor.
Applications and uses:
1. Can be used in children's toys.
2. Applicable to different audio electronic equipment.
3. For portable devices.
