Two Transistor Audio Amplifier Circuit

It is used by its self and also with a crystal detector radio.

Two transistor audio amplifier circuit. The two transistor amplifier offers a reasonably high impedance while providing a low output impedance. Apply 9 volt dc supply for better result. We have also studied how to organize the bias circuit to have feedback. Lets see the schematic diagram of the circuit in the figure 2.

Hi friendstoday in this video i have shown mini power two transistor amplifier circuit if you have enjoyed this video then pleas likesharecomment and dont forget to subscribe techsaw. Thermal stability is an issue because the. This time i add a current source to eliminate the inductor used in the last video. Two types of single transistor audio amplifier circuit designed with bc 547 transistor here first one is for to amplify direct audio signal and another one is for to amplify audio signal from condenser mic as a preamplifier.

The simple schematic diagram of two transistor audio amplifier is shown in the below. Very simple amplifier circuit using transistor 2n3904. In this amplifier circuit we are going to shows a simple two transistor amplifierin the single transistor amplifier circuit we have made a very simple amplifier with one transistor one resistor and on capacitor but. It is an ideal transistor amplifier circuit for applications where a higher level of gain is required than that which would be provided by a single transistor stage.

Feedback circuit of a transistor amplifier. This circuit can drive 8 ohm loud speaker and produce considerable sound. Using two small transistors 2n3904 and 2n3906 we can build small power amplifier which deliver several hundreds milliwats. Positive feedback which we will notice from the general audio amplifier.

Playing around more with a super simple transistor amplifier circuit. The two transistor audio amplifier has nine components including with small speakers b1 and 15volt power cell. The basic circuit is a totem pole transistor pair with small biasing circuit configuration to give small leakage idle current. There are two types of feedback.

Two transistor amplifier circuit. For most systems single transistor amplifier does not provide sufficient gain or output impedance matching.
