The LM386 is a type of operational amplifier (Op-Amp). Operational amplifiers have a basic task. They take an input potential (voltage) and produce an output potential that’s tens, hundreds, or thousands of times the magnitude of the input potential. In an amplifier circuit, the LM386 takes an audio input signal and increases its potential ...

It is given as. gm = Delta (ID) / delta (VGS) (2) To produce the desired gain three potential divider biased circuits were cascaded in series and the total gain is the product of the gains of individual stages. Total Gain = A1*A2*A3 (3) Where, A1, A2 and A3 are the gains of first, second and third stage respectively.

Amplifier harmonic distortion can not be measured precisely. Methods using two sinusoidal signals feeding the amplifier simultaneously are commonly employed to evaluate amplifier’s high-band linearity. Since the amplifier is practically non-linear, its output contains intermodulation distortion (IMD) of the two sinusoidal signals.

Assembling the Amplifier For the amplifier’s construction, I used a ready-made 1.2mm thick aluminum chassis. The dimensions were 25 cm × 15.5 cm × 4.5 cm (W × D × H). I made the wood casing from handcrafted 16mm thick birch plywood (see Photo 5). Then, I covered the wood casing in leather. Tolex or textured vinyl can also be used.

Building an amplifier is an important step in the experimental part of the project. OUTPUT AUDIO TRANSFORMER DESIGN The output transformer in a single-ended tube amplifier is the device which matches the high-output impedance of the tube to the low input impedance of the speaker load (4, 8 or 16 Ohm). To design an output transformer, it is necessary to determine the output …
Output Power of Audio Amplifier
https://amplifier.cd/Tutorial/Power/output_power.htm
A good amplifier with high power and low manufacturing costs to build is a tightrope act. In addition the elements must be often loaded to to their absolute maximum ratings. The manufacturer calculates by right into his development also that the user demands the maximum power only most rarely.

The Output Properties of Amplifiers Amplifiers are used to increase the amplitude of a voltage or current, or to increase the amount of power available usually from an AC signal. Whatever the task, there are three categories of amplifier that relate to the properties of their output; 1. Voltage amplifiers. 2. Current amplifiers. 3. Power amplifiers.
