Types of Audio Amplifiers The audio amplifiers can be categorized in many ways. On the basis of the application of an audio amplifier, it can be categorized as follow – 1) Pre-Amplifier 2) Power Amplifier A Pre-Amplifier is required for amplifying the very low input signals from a MIC or guitar. It is used before the power amplifier stage.

Acl = RF2 / RF1 +1 = 9k / 1k + 1 = 10 (V/V) AC SMALL-SIGNAL BANDWIDTH. The unity gain bandwidth of the open-loop amplifier is determined by gm1 and CC. fu = gm1 / ( 2 pi CC) = 0.0192 / ( 2 pi 500 pF) = 6.12 MHz. The bandwidth of the closed gain amplifier is simply. fc = fu / Acl = 6.12 MHz / 10 V/V = 612 kHz.

ESP Amplifier Basics - How Audio Amps Work
https://sound-au.com/amp-basics.htm
Amplification Basics. The term 'amplify' basically means to make stronger. The strength of a signal (in terms of voltage) is referred to as amplitude, but there is no equivalent for current (curritude?, nah, sounds silly). This in itself is confusing, because although 'amplitude' refers to voltage, it contains the word 'amp', as in ampere.
ESP Amplifier Basics - How Audio Amps Work (Part 3)
https://sound-au.com/amp-basics3.htm
Amplifier Basics - How Amps Work (Part 3) Now on to FETs and MOSFETs. FET stands for " Field Effect Transistor ", and MOSFET means " Metal Oxide Semiconductor Field Effect Transistor ". This topic is something of a can of worms, not because of some deficiency in the devices, but because of the huge array of different types.

This type of amplifier generally focuses on changing the character of the signal in desired ways while introducing as little unwanted distortion as possible and may provide little to no actual power amplification. An audio power amplifier ("power amp") is used to increase the signal power so as to drive a load, such as output speakers. Similar to pre-amps, power amps …
