never seen this kind of mos physics lecture ! like the very depth with in 3 hrs of duration really appriciable .

[@conquerorcj26]

learned MOS in one day thanks alot man.

[@janglipilla164]

Thank You bhaiya...kaafi cocepts clear huye

[@faneeshbansal]

sir at 33:50, there can also be one more reason for why we should always have drain to be positive as when we apply negative voltage at the drain side, the pn junction will be forward biased as we are applying -ve volage at n side and the body is already short-circuited with the source and the source value is grounded, so device breakdown will happen.

[@kollasivaramakrishna6732]

Thank you brother!!!

[@changethename4725]

Hi Himanshu i think the depletion type MOSFET can still be used as an amplifier as we know that when the incremental input is zero the incremental drain current is still zero (not the bias current) so as long as condition of saturation is maintained we can use it as an amplifier

[@user-bg4pt8ds9d]

Very in-depth, interesting & lot of good question effective reasoning is there in this unique Premiere. When are you launching this Analog course? Waiting eagerly. Also, requesting to please upload the solutions pdf for Mega test of Basic Electrical Science course. It will help us very much. Best rgds

1:23:22 How holes are getting attracted opposite to E-field?, electrons are attracted opposite to field direction

[@HimanshuAgarwal_]

Yes, That's an error from my side. Eventually, the holes are not going into the drain terminal.

Legend moment at 41:16 😂😂

[@brucelee-ot6xy]

bro plz make placement 2 course fast

[@SKSingh-el6tm]

Gate voltage is used to bias the circuit in require region .(saturation)for amplifier . So if in depetion type mosfet without applying gate voltage we can obtain saturation. For small signal at Gate Mosfet Current will still vary. So it should work as amplifier?

[@polaroid2674]

We know that the n+ pit at drain contains electrons as majority charge carrier and when we apply a positive voltage to drain,all those electrons will start moving towards +Voltage of drain ryt? Am i wrong or is there a different explanation for this? Please clarify my doubt

[@HimanshuAgarwal_]

Yeah, that's why it's getting depleted of charge carriers

[@polaroid2674]

What does + sign inside a circle mean? Does it mean a hole or an electron?

[@shanu3588]

First to get a interview call we have get rank under 100. 😢

[@debarsheebhattacharjee164]

Hi, I have enrolled for your analog interview season. How to connect with you. No link in Topmate is letting me MSG you
