Nice overview. A couple of comments: 1) In several places you used the term "exponential" when you really meant "exponent". This caused me a little confusion until I figured it out. 2) In the AC circuit at 13:14, you have the bottom of the signal and Thevenin resistance connected to Rs. From the original circuit it appears that they should be connected directly to ground.
Thanks for the feedback! In regard to your second issue, I caught that just after publishing the video. I made sure to mention that in the description, (thanks for bringing that up though!). Could you give me more details on when I said "exponential"? Are you referring to when I use E for exponential notation?
@@JJHanna Yes, in two cases (and maybe more I didn't catch) you used the word "exponential" when talking about an exponent. I think of "exponential" more along the lines of e to the x than E-3. I think in one case you said something like "we can forget the exponential", and I was looking around for someplace that a term was raised to a power, before realizing you were talking about E+3 and E-3 canceling.
I can see why you're confused. The schematic symbol for a MOSFET has a disconnected line for the gate (G). On the other hand, for a JFET, the line for the gate (G) is connected directly to the Drain (D) and Source (S). I've attached a link explaining more: www.electricaltechnology.org/2021/04/difference-jfet-mosfet.html By Ig, do you mean gate current? If so, Ig = 0 is because the gate terminal is isolated from the substrate by a dielectric medium. This is of course under ideal conditions. Realistically, there's always a minuscule amount of leakage current going through. But we're talking about pA to nA range, so we could usually neglect that. Does that make sense?
The best explanation ever , actually is it a mosfet? I’m bit confuse about the symbol, but best explanation so far, i would like to request if you can make video regarding CE + MOSFET multistage amplifier that would be appreciated. Thanks
Thanks so much! There are many ways to draw a mosfet symbol, the one I used is the more modern version. Are you used to the one with a circle around it? I will definitely make a multistage video like that in the future, I'm currently finishing off my differential equations series and then linear algebra next.

Got it, from now on I'll make sure to use the term exponent instead of exponential
Wait is that really mosfet, i thought it was JFET, a little confuse about the Ig, hope you reply!!
