Hello
I am 29 year old man working as a maintenance technician, currently I am studying electronics to enrich my knowledge to open new doors in the future. I am certain that here you will give me the help I need,
My difficulty is understanding the principle of operation and how does it work the negative feedback (emitter resistor with out capacitor) of a common emitter amplifier. I tried on the web several search attempts but didn't
fully understood the text.
What I understood was that when the collector current increases the voltage across the emitter resistance increases and this change in voltage opposes the fixed voltage supplied by the potential divider circuit and the base emitter voltage decrease(Vbe= Vb -Ve) therefore the collector current decreases and the output remains stable under all conditions as temperature ,supply variation and ac input voltages variations .
What I need is that someone corrects what I understood or otherwise confirm that my thoughts are correct.
Thank you and good wishes
