Operational Amplifier Basics: Working Principle and ...
https://www.utmel.com/blog/categories/amplifiers/operational-amplifier-basics-working-principle-and-amplifier-circuit
The actual amplifier circuit is usually composed of a signal source, an amplifier composed of a transistor, and a load. Features of amplifier circuit: 1. There are two working states of static and dynamic, so sometimes it is often necessary to draw its DC path and AC path for analysis; 2. Circuits are often added with negative feedback.
ESP Amplifier Basics - How Audio Amps Work

There are many different calculations for this, depending on the combination of components. The -3dB frequency for resistance and capacitance (the most common in amplifier design) is determined by ... f o = 1 / ( 2π × R × C ) where f o is the -3dB frequency. When resistance and inductance are combined, the formula is.

In Book 1 of " Practical Transistor Audio Amplifiers " I dealt with the basic principles involved in transistor A.F. amplifier design and the practical examples given were mainly limited to single stages. In this second book the situation is reversed and all the space is devoted to practical amplifier circuits employing all the principles and
Audio power amplifier - Wikipedia
https://en.wikipedia.org/wiki/Audio_power_amplifier
Key design parameters for audio power amplifiers are frequency response, gain, noise, and distortion. These are interdependent; increasing gain often leads to undesirable increases in noise and distortion. While negative feedback actually reduces the gain, it also reduces distortion. Most audio amplifiers are linear amplifiers operating in class AB.
