Hello everyone
I am a student of engineering in electronics & communication [1st year]
As I am a beginner I want your help.
I have been told from college to make a simple amplifier for audio.
So I don't know how to make an amplifier

so can anyone help me with this task?
I want to make an amplifier with the help of single transistor.
So is it possible to make an simple amplifier with the help of one or two transistor?
If yes then pls help me making it.
give me link or any ckt diagram with which i can build a simple amplifier.

Hello,

Here you are. Read the articles Mr. Pass wrote here and here .

The ZEN amplifier has a single device used for amplifing the signal. The other one is a current source. So here you have: an amplifier with just two mosfets.

The Death of ZEN

article written by Mr. Rod Elliott is a also very good didactic source.
