Musical instrument audio amplifier вЂ“ used to amplify signals such as music or speech.

Carbon microphone вЂ“ one of the first devices used to amplify signals.

Magnetic amplifier вЂ“ a transformer-like device that makes use of the saturation of magnetic materials to produce amplification.

Rotating electrical machinery amplifier вЂ“ provides amplification of electrical signals by the conversion of mechanical energy to electrical energy.

Johnsen-Rahbek effect amplifier вЂ“ the earliest form of audio power amplifier.

Mechanical amplifiers вЂ“ used in the pre-electronic era in specialized applications.

Optical amplifiers вЂ“ amplifying light through the process of stimulated emission.

Integrated Darlington pairs come packaged in transistor-like integrated circuit packages.ДЄmplifiers may be used in several industries such as: This configuration gives a much higher current gain than each transistor taken separately and, in the case of integrated devices, can take less space than two individual transistors because they can use a shared collector. In Darlington pair, two bipolar transistors consist this compound structure wherein the current amplified by the first transistor is amplified by the second transistor. To minimize distortion, the output stage is formed by the Darlington pair of Q2 and Q4, Q7 and Q11, while Q8 and Q9 provide constant current through the bias chain. The input signal of the circuit, as the Q1 operates in common emitter mode, is delivered to the bias chain of D14, D13, D6, Q9 and Q8.

The transistors 2N3055 and MJ2955 are functioning as power transistors because the structure is intended for power switching circuits, series and shunt regulators, output stages and high fidelity amplifiers. The 15 Watts power is made possible by using a dual 20 V power supply into a load of 8 ohms. MJ2955 вЂ“ the complementary PNP type of 2N3055.

2N3055 вЂ“ a silicon NPN power transistor intended for general purposes.

Amplifier вЂ“ any device that changes, usually increases, the amplitude of a signal.

The circuit was designed to create an amplifier that will supply 15 Watts to any load using discrete components.
