[@ggmb1032]

Thank you so much sir for your generosity of your knowledge and explaining everything so well and in detail. You are blessing and treasure to this world. God bless you and your family.

I feel that you are more important than Sedra Smith.

don't say that, sedra and smith are very old than Prof Razavi, smith alone was in his 90 before he died in the end of 2023, it's true that Razavi he initiate good initiatives to help students, but sedra and smith book still have one of the most creative learning approach to simplify microelectronics curriculm to the aspiring students

[@nikoszervo]

It is harder to understand the Sedra Smith's book, but it has some more deep explanations. In my opinion, combining Mr's Razavi lectures with Sedra Smith's book is the BEST WAY to learn as of 2024!!! Once you completely master Sedra Smith's book, you move to Arts Of Electronics (which the E-book is free by the way) and you master hundreds of actual circuit applications.

I humble gratitude to you sir. You are up there withe the best teachers there has ever been.

Thank You

thank you so much!

I think Prof Razavi's denominator in the transfer function at 43:00 might be wrong.
I put the KCL equations through a symbolic solver and got the following for the transfer function :
R_D*(g_m - C_GS*s)/R_D*R_G*s^2*(C_DB*C_GD + C_DB*C_GS + C_GS^2) + s*(C_DB*R_D + C_GD*R_D*R_G*g_m + C_GD*R_G + C_GS*R_D + C_GS*R_G) + 1.
The difference being with the square term on the denominator, where instead of C_GS*C_GB, I got C_GS^2. Not super important, but caused me some confusion.

[@GautamGarg_0]

I carried out the calculations myself, his function is correct. You must have made some mistake in between

[@fabianporras8585]

muchas gracias!

[@alexandrosanastasiou1964]

One question, at ~ 31:50 why is the transistor Current Source = g_m * V_1 considered an independent current source? This source should not be set to zero.

[@jovandrum21]

Yes, but because the input voltage goes to zero, V1 also is zero, and hence gmV1 is zero

[@inquisitortr7930]

How we write transfer function directly.Can someone explain?

[@anaseshmawi568]

you need to use algebra and etc

[@harithagb5514]

There's a separate video on that, I think it's lecture 18

[@zinhaboussi]

who tried to find the transfer function but stopped and didn't finish it xD

[@vancart47]

until this video there was no ads but in this one there is like ads for every 5 minute. is that same with you guys or only me ?

[@shaleensingh2333]

No
