About :

This video is recommended for those who want to build an amplifier or even design their own circuit and are looking for knowledge. Welcome to another video... This is one of the most important and most used amplifier stages in electronics, so I couldn't not talk about it here in this video, right? Well, well! In addition to being widely used in audio applications, it is also widely used in DC (e.g. “Interface” with micro controllers). Its main function is to provide voltage gain and also to make the correct impedance matching between the amplifier stages. In this video I try to simplify its function as much as possible and I also make some comparisons between it and the input stage that make up the complete class AB amplifier, and at the end of the video I show a simple topology of a class AB amplifier that will be the subject of a next video.
