Electronic Devices: MOS Capacitor (08) - Non Idealities : Flat Band Voltage

Non Idealities in MOS Capacitor (MOSCAP) are discussed:
work function difference b/w Metal and Semiconductor
Charges in the Oxide
Threshold voltage changes from Ideal to Practical MOSCAP
CV characteristics shift and Inversion charge density discussed in detail.

i've seen your videos of 'MOSCAP' (51 to 58) and they are awesome . I think your style matches somewhat with solid state devices book writer "streetman" because you always seems to emphasize on the fact that we draw Energy band diagram for -ve charges aka electrons in your lectures so that we don't confuse it with electrostatic potential energy of positive test charge (U) that we read in class 12th physics.I'm very satisfied with your intuitive explanations & less mathematical clutter unlike books like neamen.I urge you to please make more videos on Advance electronics VLSI design part,Elmore delay calculation,interconnects ,Noise margin analysis ,trip point calculations of inverter & go upto digital VLSI design Level 1 spice model.Because these topics are very rare to find on KZbin.This way your lecture series will be very fruitful to many indian electronics students who want to enjoy EDC from basic device physics to Digital IC design part (a very smooth transition from EDC to IC design)................I've already subscribed your channel , looking for more videos to come... .thanking you

Best explanation one can ever come across of MOS Cap. Couldn't find anywhere else. Thank you so very much.

[@sohamlakhote9822]

This type of lecture literally deserves an attention like a bollywood movie!!Even the IIT professors have hard time explaining this topic. The only lecture which explains it clearly other than you was lecture of MOS capacitor by CALTECH prof Ali Hajimiri!!!Your conceptual clarity is really good and you are able to impart what you have understood which requires good skill. Hats off man and please continue to post such videos!!

[@harshniketandixit9320]

best explaination brother.I searched a lot bt i got it here.

[@parthadeb753]

The best playlist I have ever got.Thanks a lot.

[@umasankarcherukuri6483]

I've been struggling a lot to understand this concept for days. I referred several books which some of them were good but still the terminology is quite inconvenient. The new terminology and concept of work function itself is difficult for me. You've explained these topics beautifully. Thank you. Keep Going!

[@techgurukula]

Thank you umasankar. Yes, will keep going!

[@asadmamun5772]

Excellent Explanation

[@vallidevasenaananthabhotla4174]

I always had EDC phobia right from by B.tech your content has made me over come that. Thank you, your lectures really helping me for my Gate preparation.

[@PredatorF-25]

Thank you Sir, awesome explanation. This ended all the confusions that were prevailing in this topic.

[@NehaSharma-wx2rc]

Amazing explanation. Not available anywhere but here

[@simonblue56]

I’ve watched the first seven videos which indeed helps a lot. It seems everything is simple with your explanation. By the way, I like your handwriting.:)

[@techgurukula]

Thank you Simon! 🙂

[@aakashgupta4478]

I don't get EDS as easy before ,, You explain in very easy way,, Hope you would make more videos.

thanks for your video!!!

[@mohammedaftabbaig9858]

Very good explanation sir, I read std. books but my concepts became clear with your lectures

[@user-qn9qc2wn4h]

Great lecture 👍

[@Vi-vp3us]

Please share the notes. Thank you very much for this video :)

[@tusharrohilla7154]

Thank you so much bro.. Cool

[@yepnah3514]

Hi how do we graph the SOS C for an NP (p is connected to ground and N to Vg).

[@mitchellmckay5448]

So on topic thank you

[@user-uc5tq7gh2e]

Excellent!

[@pavankori6986]

I like your video and so helpful please update your video and also make a video on differential amplifier OTA and other thing like gilbert cell

[@xAmiSarahx]

good evening sir...thank you for helping me with my exam...

[@kousikdas9177]

Hello sir, in this video you mentioned about IC technology processes. When will you publish those videos? Especially the twin tub CMOS fabrication process is very much required from my side. Thanks for all these videos anyway. 😀

[@amitmishra-mv3in]

Exception work sir...:) It will be helpful if u provide the text which u have written while explaining...:)

[@HhhHhh-et5yk]

Sir! When will u upload IC fabrication? Please consider

[@coolwinder]

Why would fermi levels in metar and semiconductor be different? I understand fermi levels as potential energy of all electrons on that distance x. If they are different would that mean electrons would like to go to the semiconductor even without anx extrinsic field, is that due to diffusion, as metal has way more conduction electrons then semiconductor?

[@HarshBhatt1996]

Can you please make a lecture Series on MOSFET parasitic Capacitance (which will include overlap, junction and channel Capacitance ). thanks for MOS CAP lectures.

[@manikantaaare5748]

Tq sir .

[@youcefai619]

thanks

[@alirezafarzad7789]

Could you please link the picture of your notes too?

[@tusharmishra-untoldfacts1861]

Why we need flat band condition?

[@allachandrahas7951]

sir, please teach metal-semiconductor interface also

[@rr8055]

Sir can u tell me what is meant by work function

@@techgurukula excellent explaination of the theory

[@madhavaraopabathula3572]

Gd work sir , do analog circuit classes

[@techgurukula]

@@madhavaraopabathula3572 Yes, will be doing analog circuits after completing Electronic Devices.

[@techgurukula]

@Kaushal Joshi will be starting Analog circuits with new setup - best case in a week or two

[@vijayrajchoudhary5206]

sir plzz plz upload OSCILLATOR CIRCUITS FROM ANALOG TOPIC...GATE 2020 is almost here..plz help us in that topic sir

[@Vishalkumar-ez5xy]

Sir, in Charges in the oxide, can Qox be negative?

[@captainstreamer3261]

Yes , Offcourse It Can ,, then put negetive voltage in the place of Qox in equation in VFB ,,, This VFB equation Does Not Change Over P - Type Or N - Type Substrate This VFB equation will work for both

[@vivekupadhyay6663]

Do these videos cover the GATE syllabus ??

[@techgurukula]

Yes, exactly. Covers GATE syllabus.

[@ajinkyashantnu9399]

Net electric field is wrong at 13:00

[@captainstreamer3261]

problem of this playlist is you derive only one equation Suppose , You Want To Derive Threshold Voltage For MOSCAP , You Derived only P-Type MOSCAP equation and SKIP ALL THE DIAGRAMS AND ALL THE CV CHARACTERESTICS AND ALL EQUATIONS FOR N -TYPE .... now suppose in some video that also include , that will get high ratting than you ,,, you have great potential but try to present it completely , thus student have no question to ask at least in Initial stage ....
