Hi,
I am building a low-power FM transmitter based on a pre-existing design.
The first stage is a simple discrete audio amplifier consisting of one NPN transistor (see attached picture).
I would like to understand and adapt it.
I think I have the minimum education concerning bipolar transistors (Ebers and Hybrid-Pi models).
But I am not very familiar with feedback on transistor level. I often see some qualitative statements concerning the effects but no rigorous development.
Could you recommend me a book which addresses feedback at transistor level ?
Thank you.
