Thank you professor for showing how to use B and G and how independent gain affects stability - a lot of data sheets just pussyfoot around the issue and you showed a completely deterministic way how B resistor affects stability and how to verify it.

Thanks. Yes, I find the G and 1/B an eye openers. Thanks for the note.

Dear Professor, Thank you for the inspiring lecture. Since starting my PhD four years ago, I have greatly benefited from your lecture videos on UA-cam. I am now preparing for my PhD oral exam, and many of my recent publications(TPEL, TCASI, ASSCC, APEC, and ECCE ) have been inspired by your papers and lecture videos. Thank you once again.

[@sambenyaakov]

Thanks for taking the time to write this kind note. Comments like yours keep me going.. Send me references to your papers. you seem to be very prolific, Good luck with your defense.

Hello Professor, I am Chieh-Ju Tsai from National Taiwan University. Although I publish extensively in the Power Electronics Society, I believe my research represents incremental innovation. You can find publications from my advisor and our lab here (scholar.google.com.tw/citations?user=1BM6wt8AAAAJ&hl=zh-TW). Our work mainly focuses on the modeling of constant on-time control. Very thanks to your lectures on UA-cam, again.

Superb presentation, a model of clarity on a subtle subject I did not understand. Thank you.

[@sambenyaakov]

Glad it was helpful!. Thanks.

Thank you sir for great presentation.
Sir could you please make video about theses subjects? Thank you 🙏🙏🙏
1) How TL431 works in feedback circuit of SMPS.
2) How to connect switches (IGBT and MOSFET) in series and parallel and what are the consideration.

[@sambenyaakov]

Good subjects. Will try.

Hi Prof. Could you please also have realization design too. It would be nice if you made it with discrete transistor solutions.
I made it with discrete transistor in practice but couldn't get BW constant when I change the gain .
I did it like Author Sergio Franco.👋👋👋👋

[@sambenyaakov]

He shows discrete circuit for CFA?

[@Zetex2000]

Thank you very much for your presention. I am learning a lot from it. I believe the Norton Amplifier is also considered current feedback amplifier?
