Input Stage The input stage to this amplifier has 3 main parts: a differential BJT pair, a current mirror BJT pair, and a constant current source. Connected to the bases of the BJTs in the differential pair are the input signal and the negative feedback coming from the output. The differential pair generates an error signal that drives the output.

Audio power amplifier is a key part in stereo system. It mainly consists of three units: pre- amplifier unit, tonality control unit and power amplifier unit. The simple block diagram is shown in Figure 2. Every part will be explained in detail. Figure 2 The simple block diagram of audio power amplifier 2.1.1 Pre-amplifier unit

Amplifier Design Project Sections 2.1 to 2.4 of this module are a practical project to design a single stage class A common emitter amplifier. Use information from other sections modules in learnabout-electronics (just click the links where needed) to help you calculate the component values needed for a working amplifier. The only maths involved will be some Ohms law and …

1 - Input Stages There are two main possibilities for an input stage for a power amplifier. The most common is the long tailed pair, so we shall look at this first. It's not uncommon to see two long-tailed-pairs, one using NPN and the other using PNP transistors.

Week #1: Audio amplifier Week #2: Microphone circuit The audio amplifier project is more difficult and time-consuming than the microphone pre-amp, so part of week #2 may be used to finish the audio amp. All breadboarding and testing can and should be done in lab. Soldering and hardwiring can and should be done outside lab.

there must be 4-stage LED indicators corresponding to 0.25V, .5V, 1V, and 2V output levels for each channel as well. The system is run from the normal household wall socket supply of 120 Vrms at 60Hz. The design can be adapted to accept input from any type of audio plug. Output is adaptable to normal speaker wire.
Distortion in power amplifiers, Part II: the input stage
https://www.eetimes.com/distortion-in-power-amplifiers-part-ii-the-input-stage/
The input stage of an amplifier performs the critical duty of subtracting the feedback signal from the input, to generate the error signal that drives the output. It is almost invariably a differential transconductance stage; a voltage-difference input results in a current output that is essentially insensitive to the voltage at the output port.
