In steady state wouldnt the poles of the system oscillate around the jw axis as the gm keeps changing with amplitude? Why would it converge on the jw axis?
One question: when there is a resistance zero associated to an inductor, the time constant becomes infinity as you showed on the video for the negative resistance circuit. Happily on that example you can work with another time constant. How do you deal in general with those situations? Thanks an congratulations for your great videos.
Often, you can find a combination of the time constant products that gives you non-zero, non-infinitely products. But if you cannot find such you can always add a small series resistance, rx, in series with the inductor, do all the calculations (with finite resistances) and then set the value of rx to zero.

Amazing lecture!
Very good videos. By the way, where would be the previous videos on circuit theory ?

@@AliHajimiriChannel Hi Professor, In the last example circuit with C1,L2,L3, the T32 = L3/R, however you calculated L3/ꭃ=0. Howcome?
@@gauravshrivastava6150 Because left side of L3 is open circuit, so the resistance associated with L3 is infinite value because of the open circuit.
so well explained
Is there any way to get the Homework packages of this course?
The part where "Gm" is calculated seem missing
Omg.... you are describing the fundamental behavior of the entire Universe - Electron.
