Razavi Electronics 1, Lec 42, Op Amp Circuits 1

Op Amp Circuits I (for next series, search for Razavi Electronics 2 or longkong)

[mohitupadhyay]

such a good effort to spread knowledge and that also free of cost. Real knowledge make people good inside-out.
thanks from INDIA

[jdmc]

You sir deserve a medal. Heart felt THANK YOU for an OUTSTANDING LECTURE- I salute you.

[manishsolanki]

Best Analog electronics lectures I have seen

[maximecholvy]

Great explanations, once again. You care about leaving nothing that could be misunderstood. That's very appreciable.

[imankian]

This is great!
We're waiting for the next

[rajivdey]

Respected sir, you are great I think I have not seen anybody in this world who teaches like you hates off

[inspectormag]

As an Iranian engineer, I am so proud of you! Professor Razavi! I found your name in a reference and searched you then and found you are a great Iranian-American professor and you have many lectures here. I am not electronic engineer but being an electronic engineer was my dream from a long time ago when I was a teen and used to make some electronic boards or repair some stuffs and now I am very interested to learn and study by myself. Thanks for your great work to students! stay healthy!

[arjunp]

Thank You Prof Razavi for the wonderful lecture

[khuongtranminh]

What an incredible explanation! Thank you, sir!

[habtamusium]

nice presentation ! quit understandable
thanks!

[psrikrishnareddy]

excellent work sir...
Waiting for more videos on Analog circuits

[youcefaitamrane]

Dear Mr Razavi. I'm very greatful to you for the lectures you are providing on Youtube. Excellent pedagogy ! Do you give lectures on Communication ? Kind Regards Youcef

[abhinavsingh]

sir, i am eagerly waiting for next series, please make it sir.

at 52:28, the gain of this CS stage is directly used to derive the open-loop gain, but isn't the gain of CS stage only valid with a small signal? with this Vout swinging, it is more close to determining the quiescent operating point of the CS stage in my mind. So why shouldn't we concerned about the validaty of using this small-signal gain in "big" signal analysis?

[黄河黄]

The last equation of inverting op with A0 not very large, the voltage gain = -1/(R1/R2+(R1+R2)/A0*R2), is that right?

[richardgray]

Who teaches electronics better than Dr. Razavi? Nobody, that's who.

[divyanshuvadehra]

Why didnt that op amp given in the quiz not saturate despite being connected in positive feedback?

[dushyantbansod]

I need the same quality lectures for Network analysis, please suggest if anybody knws

[MrVasugupta]

When is the next series of videos coming?

[toddmoore]

why doesnt current through R2 enter opamp because output impedance of opamp is 0 ?
