Highly recommend this lecture series to gain a solid understanding of Feedback. Prof. Razavi's explanation will help clarify things that most people take for granted.
This lecture is the BEST explanation. I used to blindly make sign convention as negative if a signal is going from gate to drain in entire signal path. final summation of all signs gives me feedback sign. But that's not the best way to solve. It's very clear now. Thank you sir 🙏🏽
