Pure genius and an absolute masterclass from the "God of Electronics". His way of building up the things along with why they are needed before telling that this is what we called as '---'(e.g MOSFET) is brilliant and creates enthusiasm in the person watching the video. He should deserve a prize for his way of teaching!!. Keep it up sir, you are doing a great job!!!. Love from India.
Thank you so much! Explained with perfection. Told every necessary detail. Now I want to learn it unlike in university where our professors teach us like we know everything already. I can't thank you enough!!
Engaging, informative, easy to understand and thought provoking…Never ever came accross such style of lecturing before….always thought of seeing you since Engineering days Prof. Razavi….your books are very popular among Engineering students community in India…..I am currently revisiting your RF Microelectronics text book’s 2nd edition…..thanks a lot for your contribution to the electronics World and for uploading these youtube videos….can’t thank enough to the uploader….Masterpiece!
the best lecturer. as my age is lesser than his experience you earned my respect mr razavi one word i want to say to you the best faculty i've ever seen in this generation.
Exceptionally excellent lectures. Prof. Razavi is great. The whiteboard and the pen are high-tech as well. The manufacturer should make one small improvement - make the other end of the pen as an eraser so professor does not have to use menu system to select an eraser function. That will emulate a pencil better and save professor time.
Hi that is a great , idea. i am studying electrical engineering and i happen to be also doing motor and generators, would you know who teaches them well here on youtube or anywhere is there a websites
Hallo Beautiful people, i dont know who is here in 2024 but i needed help with motors and generators i dont know who teaches those well like DR Behzad Razavi does an outstanding Job at teaching us Analog Electronics here.
sir please upload electronics 2 lecture .we love your lecture ,it is super ,most of my confusion get clear by your videos .sir please upload as soon as possible thanks so much sir
Can any explain what happens to holes in p type semiconductor as he took only about electrons in consideration ,if we invert the voltage applied between semiconductor and capacitor as holes are more in p type it conducts more current. 15:03 min ?
I went through transistor lectures first in this Electronics 1 lecture series. Views decreased as the transistor lectures went by. Lec 28 is the last lecture on transistors. Suddenly in the middle of the lecture series, this Lec 29 has much higher views than Lec 28. It feels like new students have joined us like in real life in a university class 😄😄
at 29:42 he compared B to source but that would mean source is at lower potential than drain ,also in next video we heavily use the term Vgs and say its V gate source,can someone tell how if sir have already said mosfet are symmetric,shouldn't its be V gate substrate?
17:50 It does not follow from Charge increasing that Charge Density increases. If the volume/area/length of the distribution of the Charge also increases then the Charge Density could remain the same or even diminish. Charge Density isn't defined, so that's very unhelpful. Wasted a lot of time trying to figure out what was going on.
But the volume, area and length are constant. Free electron density increases in the are between source and drain because that's the point where we apply Vg. Charge density is the number of charged per unit volume. Basically, in the channel connecting S and D, more free elections gather this reducing resistance of the channel which in turn increases current
Hello prof razavi I have a question please is there a standard certificate of electronic circuit design only not related to any college and if it existed is there an online test for it
if charge goes away from one type of material to other,then only ions will form.but here holes are move away from ptype material itself.then how ion will form here?
This is kind of classes is the reason why I don't like our University Teachers and curriculam. All that is important in our curriculam is completing syllabus in light speed, give assigments and take exams, and grades that you will get only memorising with out deep understanding.
i did not understand why source and drain are highly doped n type materials. if it is for making good contact between metals and material then my question is in case of PMOS we use P+ type materials for source and drain. I want to know the noble cause for using them ?/ What i thought is depending on the channel source and drain are doped with corresponding materials for the smooth flow of charge carriers is that correct or any answer?
Yea UA right.....the thing is highly doped in the sense...would create more free charges ...electrons for n+ and holes for p+ thus making a better channel to be formed btw source and drain.. :)
The contact is so small and we want to flow high(relative) current through the source so we need to put either a wide connection to the source and drain or we can make a higher dopping
in 52 .50 we assume that vd>vs; and vs is ground. what if vs > vd and vd is grounded.is the result would be current will flow from drain to source like pmos. can anyone explain this
For a textbook-use MOS, I think the answer would be YES! After all, Observation 2 at the bottem right of the previous page says this device is SYMMETRIC.
Is there any particular reason to NOT draw a dependent source as a diamond? I have always drawn it that way, and it doesn't seem any more awkward than drawing a circle.
These are not free e s exactly. These are minority carrier present in ptype semi conductor accumulated at the cap plate due to inversion forming a channel
As long as these videos are available on TH-cam, VLSI engineers don't have to worry about anything...♥️⤴️

Whoopto
Almost any one-" I don't care why MOSFET got that shape"
Prof. Razavi-" let me tell you why"
Jokes apart, Huge respect for your efforts sir 🙏
We need Electronics 2 set of lectures from Prof. Razavi. We love your lectures professor.
Thank you so much! Explained with perfection. Told every necessary detail. Now I want to learn it unlike in university where our professors teach us like we know everything already. I can't thank you enough!!
many years studying electronics and this is the first time to have a clear understanding of "how and why mosfet is shaped like this"
He really played with semiconductor physics..Amazing Professor.

Thank you, B. Razavi Sir, finally we get blessed to enjoy your lectures. And to learn from your lectures.
Sir you are a gem. you are one of the best faculties . your teaching made me a better analog engineer thank you for your contributions sir.
the best lecturer. as my age is lesser than his experience you earned my respect mr razavi one word i want to say to you the best faculty i've ever seen in this generation.
One of the most excellent and super legend professor on earth 🌍😊
my god never seen such an interesting and simple explaination of mos before
Exceptionally excellent lectures. Prof. Razavi is great. The whiteboard and the pen are high-tech as well.

Thank you very much Mr. Razavi for this amazing explanation!!!. Saludos desde Puebla, México.
Really, Genius, Thank you sir for providing conceptual videos
please upload electronics 2 lectures..these ones are great =D
what is electronics 2 lectures
I learned new idea of learning from You much thankful respected sir
Thank u sir ...............got a new way of understanding mosfet...........
King of analog cmos design Love from kashmir
love ur lecture and the way of teaching thnk u soo much sir...
Hallo Beautiful people, i dont know who is here in 2024 but i needed help with motors and generators i dont know who teaches those well like DR Behzad Razavi does an outstanding Job at teaching us Analog Electronics here.
respected sir your are a wonderfull teacher a watched your all lectures sir i request to you that plz upload transistor as an ampifier lectures
sir please upload electronics 2 lecture .we love your lecture ,it is super ,most of my confusion get clear by your videos .sir please upload as soon as possible thanks so much sir
Charge Density is eventually defined in Lecture 30, MOS Characteristics I, at 32:30 - a bit late in the day for the present lecture.
Absolutely amazing , how simple he describe the MOSFET working principle.
🙏
thank you for ur work sir.. have a great day
Finally I begin to understand, thank you so much.
Can any explain what happens to holes in p type semiconductor as he took only about electrons in consideration ,if we invert the voltage applied between semiconductor and capacitor as holes are more in p type it conducts more current. 15:03 min ?
God tier lecture 😭

Brilliant video! Very intuitive explanation!
Fantastic!! One question: why does increasing VG bring more electrons into the channel?
عم رزافي, واحشني يا جدع 😍
Easy to understand, thank you sir.
Very Good Lecture
Amazing, again.
What a lecture! Thank you Sir
at 29:42 he compared B to source but that would mean source is at lower potential than drain ,also in next video we heavily use the term Vgs and say its V gate source,can someone tell how if sir have already said mosfet are symmetric,shouldn't its be V gate substrate?
Comprehensive and informative.
amazing video
bro if you have the lectures for Electronics 2 then can you please upload them? thanks in advance :)
This man made me interested to learn holy
His Highness Professor Behzad Razavi !
people who disliked this video don't deserve education!
خیلی عالی بود ...
This starting music has a separate fan base
Excellent lecture!
Thank you sir
You are a GOD...

thankyou so much Sir, you are great
simply genius...
Hello prof razavi
I have a question please
is there a standard certificate of electronic circuit design only not related to any college and if it existed is there an online test for it
@Long Kong can you upload Circuit Theory I & II Please
Why is a p substrate being used? N type will have more of free electrons. Wouldn't it be better for forming a electron channel?
This is a way to control the flow of electrons using Voltage at Cap
we cannot get electronics lecture 2,I have emailed him regarding that but he said he never got a chance to produce them
if charge goes away from one type of material to other,then only ions will form.but here holes are move away from ptype material itself.then how ion will form here?
Where are the 90 second quizzes?
Where is 90 sec quiz which is mentioned at the start?
Better than the Idi ot s at UTEP
What's the title of the music in the intro? :)
love you sir
Lovee you❤❤❤
What kind of whiteboard is he using? I've never seen that before.
it is a touch screen display
nice lectures

from where the free electron come?
These are not free e s exactly. These are minority carrier present in ptype semi conductor accumulated at the cap plate due to inversion forming a channel
Thankyou sir
amazing
Sir why we use p type substrate
Mohit Bansal there’s no restriction. We can use ntype also. Just channels will be formed by holes.
Thanks
