Razavi Electronics2 Lec1: Introduction, Cascode Current Sources

[dongding]

im so addicted to the lectures that i was teaching my cat to bias a FET in saturation in my dream.

This chap should get a nobel prize for for sharing knowledge and making such a big impact on peoples lives. He is empowering people in the world of electronics in a way that very very few can. I have never come across a lecturer like him either online or in the real world. Thank you professor.

[hemantj]

This time don't leave us begging for more. We have waited for a long time for these lectures.

You are amazing. You make it look all easy and interesting unlike others.

Thanks for your affection towards us

[moshmo]

These are by far an away some of the best lectures I've attended. Very rarely has a professor been able to keep me interested in the content while also being so thorough. Thanks!

01:25 - Intro and review of Electronics I and II
10:28 - Examples of Circuits of Interest
14:45 - Current Source with MOSFETs
24:07 - Improving Current Sources with Degeneration
33:20 - We need a device that can degenerate but does not follow Ohm's Law - That offers same or higher incremental resistance - That will serve as an negative Current-Voltage feedback element
39:20 - Fundamental Property of Cascode
42:40 - Double-Cascode
45:00 - What happens when the widths of transistors in a cascode are doubled?

Boss is back in you sir for the lectures

# KING OF ELECTRONICS IS very fortunate to have him again..

[srikanthm]

Thanks a lot Prof. Razavi for hearing out our requests and taking out your time for making this video lectures for free.

[francescosanna]

Thanks for being alive in this
Oh professor, my professor!!!

[eliabramov]

Thank you dear Prof. Razavi for your valuable efforts!
Also big thanks to you Dr. Kong for uploading the videos.

These lectures are priceless!

[tze-ven]

This is why we need true expert to teach this subject. I never knew the true reason till now. Everyone else gave unnecessarily complex and confusing reasons. Thanks Prof. Razavi!

[sanjayd]

Brilliant teaching. This is a refresher for me but I wish you were my professor while I was pursuing my MSEE degree and took a class on Analog IC design at a university in the Chicago area. I love Dr. Razavi’s RF Microelectronics textbook.

Dear Prof. Razavi,
You are very different from many other lecturers on electronics, because you love what you teach..
And we are your devoted students, because we love what you teach.. We also love your style..

I beg on my knees: Please continue.. There are so much more in your mind to teach us..

[mohamedabdirahmanabdulle]

really i have never seen any teacher explaining like prof. razavi but what i like to say is thanks million times prof. razavi i wish long and health life and request to continue helping hungry the students for your knowledge.

[sahhaf]

Thank you very much, Mr. Razavi, or should I say king of us all? I cannot sufficiently express how much I like your books and video lectures. You love electronics and it shows at every second of your programs..
Needless to say, we all hope for electronics-3..
Best regards from Turkey!!

[mdwaliurrahmankhan]

Sir, you are an incredible Professor. I truly thank you from my heart.

[aerodynamico]

I read his book, fell asleep. I found his videos on YouTube, now I can't sleep! Thank you, professor!

[ayushkumar]

I am in love from the first lecture itself, but I can not comment on every lecture because viewing ur lecture seems more important than my comment but I really feel very good to see people like u, who put there whole life efforts knowledge to share so effectively..

ur all-time student.
:)

[prolawren]

easily the best electronics 2 class on youtube !!! Thank you soo much. these videos are very helpful !!

[slayerxyz]

Thank you so much for making these videos. These videos are the best resouce for building a good understanding of transistor circuits I've been able to find on the internet.
