Razavi Electronics 1, Lec 20, Common-Emitter Stage

[@himanshuful]

Some of the best dialogues by Prof Razavi in all video lectures 1. The circuit doesn't bite 2. This pen is becoming crazy 3. But first we don't panic

[@hpvide]

😁

[@babubb3445]

I like his attitude.🙂

[@jagatveeryadav5761]

One of the greatest Professors I've ever seen. Respect from India!

[@utkarshpant5297]

Prof. Razavi You're *GOD* of Analog Electronics for undergraduate students. This subject used to haunt me when I tried to study from Microelectronic circuits by Sedra and Smith but you made one of the toughest subject of Electronics Engineering a Child's play.

[@Upgradezz]

This scared me when I tried to study it from millman but this is just so lucid

[@michaelcostello6991]

Very useful to know these two books are far from perfect before purchasing

[@musicphilebd9862]

One of the best teachers of all time, no doubt. Much Respect

[@wagsman9999]

Wow. If there was a Nobel Prize for teaching, Prof Razavi would get three or four.

[@ahmedsamir7451]

VCC is also known as "V Common Current" as it's the voltages that supplies current to the whole circuit I truly wish I found this playlist sooner, Thanks for your efforts Professor

[@EslamMohamedX]

You're really a pure talent. In my university we're being taught ur book, so you were mentioned by my prof. I turned the YT upside down searching for your channel 'till i get here. Thanks alot.

[@michaelcostello6991]

Im glad you refresh our memory as mine is terrible

[@r1e2y4]

Professor Razavi is a blessing to mankind! These videos are gold!

[@joydeepdebnath9741]

I never found a simpler way to describe someone the meaning of AC & DC ground. You sir, are a legend.

[@GauravSingh-cs6he]

Dear Prof , You are one of the best professors I have been learning from. I just hope you teach more and more subjects and put in te youtube for us to share and increase knowledge....I am very thankful for your lecture series! :)

[@mauricedemel6142]

Very nice teaching.Godblees you.! Sir.

[@s_saidkonate1755]

you the best of th best!!!!

[@mathandphysic4393]

Thank you sir for such a nice explanation

[@sahhaf1234]

@15:10 but isnt vout change polarity depending on whether we measure it against vcc or against dc gnd? Does this carry over to small signal model?

[@k.k.skesava7561]

Doubt: @11:44 sir said that in practise we prefer the output taken across the CE rather than accross Rc . I would like to know why.

[@rinkipanchal846]

Brilliant sir

[@sam1tim316]

I think we should have added the output resistance r[o] of the transistor to the small signal model of the common emitter amplifier such that the resistance that converts the current back to voltage will be the parallel combination of the R[C] and r[o] unless we assume that r[o] >> R[C]

[@sam1tim316]

Oh ... Prof. Razavi said that he ignored V[A] or the early effect so r[o] was not included .. i commented too early :)

[@mnada72]

Is there play list by this legendary professor for circuit theory as mentioned at the end of some videos

[@Peter_1986]

Couldn't the branch with the input signal at 18:40 be simplified as well, just like the constant voltage source? I personally think that this looks even better when I draw it in that way.

[@kiromaisus]

I am searching for a video that talks about the load line (AC and DC) when using the common emitter design, but I don't think he mentions. Much respect.

[@KrishnaDN]

perfect...:)

[@AhmedDeedatPalestine]

I feel I am in safe hands.

[@Upgradezz]

Stardust!

[@williamgarcia1217]

48:47 what about reducing VT?

[@leostrauss8643]

That concerns lowering down the temperature

[@oguzhanertas7443]

59:08 :))))

[@harshitkakodhiya7540]

45:25

[@wantedq8332]

I would rather professionals make videos like this instead of writing useless confusing books.
