[@vincenzocarollo8376]

great video prof, explained very well! Can you explain a similar BJT schematic with an amplitude feedback like AGC (Automatic Gain Control) please? This is a particular circuitery used in the radio receivers or microphone amplifier to avoid saturation in chase of received signal is too big, for example adding an envelop detector in the feedback. thank you!

[@STEMprof]

You are welcome. Thank you for watching & encouraging comment. Glad that you liked this video. Thanks for your suggestion as well. Sure, I'll prepare a BJT transistor circuit with Gain Control. I'll post it in my Analog Circuit videos collection kzbin.info/aero/PLrwXF7N522y4c7c-8KBjrwd7IyaZfWxyt.

You are welcome.

[@mauricedemel6142]

THE PROBLEM IS , WE HAVE TO USE VERY HIGH VALUES FOR VOLTAGE DIVIDER BIAS NETWORK .IS IT OK?

[@STEMprof]

As explained in the video, yes, as long as the current through bias resistors is considerably larger than the base current of the corresponding BJT transistor.
