[@berkylmaz1305]

Brilliant explanations, excellent examples. Thank you for your help.

[@barancan_snmz]

he has amazing teaching methodology

[@ggmb1032]

Thank you so much sir. You are a very important person to the world. God bless you and your family.

[@alexandrosanastasiou1964]

Thank you a lot. You've really helped me with my studies, professor Razavi !

[@sumitasahu329]

You are so AMAZING!!! The way you explained the transformation of pmos configuration from nmos is sooooooooo beautiful, you made it so intuitive and easy!

[@rohithbhaskar8465]

Waiting for this from long time sir... Thank you so much 😊

[@Sourav_Soumyajit]

The wonderful explanation that everyone deserves!

[@ahmadk.jallad3691]

the best ever prof. in the earth

[@songjames9019]

Thank you! Dear Prof.Razavi

[@musaibshaikh5075]

thank you Prof.Razavi

[@spkulkarni162]

Great lectures blessed to find

[@YZ_ACM]

I love you from the bottom of my heart

[@bp4422]

Thanks a lot, Prof. Razavi !!

[@coolwinder]

11:18 - Explanation from Lec1 when we said we want an element that doesn't obey Ohm's Law.

[@gevorggeghamyan1718]

Great Teacher

[@p.r.ratnarajukunapareddy2552]

Excellent Sir, thank you sir.

[@charleslego385]

Thank you! This is extremely helpful.

[@coolwinder]

39:00 - If there were feedback, would it matter if we are applying voltage and measuring current or opposite, when finding output resistance?

[@parulgupta9989]

sir your lectures are the best....thank you sir

[@tomurkin5563]

Thank you for the video.
For the ac short in 36:30, the measured current is between the output node and ground?

[@kyounghobaik5412]

Thank you professor!

[@AnimationsJungle]

41.00 why is there a negative sign for Av ? please explain

[@armanmanukyan1970]

Thanks a lot. But where did minus sign came from in the Av = -Gm*Rout?

[@swetashreemishra4979]

because of the direction of output current.

[@alyssagarcia2417]

For bipolar transistors if the current is flowing from a Q1 emitter to Q2 emitter does that still count as a bipolar cascode? In Lec. 1 you clarified how the topology doesn’t work with mos connected source to source. Would love verification.

[@alachenchaiah4799]

thank u so much....

[@ahmedanwer6899]

i lOVE THAT INTRO MUSIC

[@teddy619]

Thank you!!!!!

[@vikramyogan2501]

In 17:54, why is gm of mosfet is less compared to that of bjt? Though prof has mentioned that it is beyond this course, if someone know... do tell me....😊

[@gauravkaushal1037]

I guess because gm in bjt follows exponential relation while that in mosfet it follows linear.

[@pritam4622]

Question>>> why we call CC/CD amplifier even they have gain close to unity ?

[@joydeepdebnath9741]

I liked the music of electronics 1 more.

[@cywinewind]

Thank you so much!

[@bitvision-lg9cl]

Maybe depict the linear circuit as a two terminal device, then we acually back to the normal conductance concept, that's more understandable, cause transconductance is still conductance whether is trans- or non-trans-.

[@raminrajabioskouei781]

Thanks

[@tatierlina6463]

Can anyone please give me the link of Circuit Theory I and II, I have searched it but failed to find it...

[@mnada72]

I don't think it's published yet

[@mrpossible5696]

Ty

[@rehanakhan5704]

Can we download the solution manual of analog CMOS integrated circuits?

[@yeohoonyoon6524]

Where does the minus sign in Av = -GmRout come from?

[@Murrummba]

it is explained in a previous lecture in Electronics1, Lec 20

[@engineeringteam-jm9xu]

GOOD

[@Embedded-Edge]

🔥

[@nageshwarburman8819]

with due respect sir..Rout for bjt isn't clear to me... everywhere i see it as r0|| Rc.. in this case Rc is not present...so r0.. and the part where u include r(pi) in the expression is also unclear

[@eliborokhovich943]

review the electronics 1 course

[@mrpossible5696]

30:00

[@rachitjoshi23]

why there is humming noise randomly. Its very irritating

[@dantecpp]
