Writing impedance from any port of MOS configuration|| Intuitive Analysis || Prep for interview

First video on MOS

[@HimanshuAgarwal_]

Correction - at 10:15 I mistakenly used word "bias" instead of "Ground"

[@IcRDlayout]

Definitely

[@kollasivaramakrishna6732]

💯💯💯

[@chandraprakashsaini1115]

brilliant videos brother.............its the intuition that needed to be strong and these videos r very helpful for that.....thanks a lot

[@chxyz9803]

Sir 8:55 pe samajh nhi aaya kaise output impedance nikala aapne!!

[@nitesh8293]

Thanks Himanshu

[@sharathchandra4194]

Hello brother, I did not understand why have we not taken r0 into consideration. Please explain.

[@mainakseal5027]

what would be the output resis of nmos with current source at the S side ?

[@kaushalrathod1723]

in thrid configuration you take Rd = 0 i mean shorted so why ro is not comes into picture why not Rin= ro || 1/gm ? time 7:55 you take 1/gm only while writing input impedance. you can simply see from above configuration just put Rd = 0 in Rin = (ro||1/gm)+Rd. time 5:44 .

[@HardikJain_YT]

Yes ro || 1/gm

[@lokendrasinghlodhi718]

At 17:08 you must have assumeed ro= infinite right?? Otherwise theoretically Rd and to will come into picture!

[@priteshkumar6963]

Can you please give me some more questions or some other related to intuitive analysis of impedance.

[@divasks8773]

do we need to short all ac sources and dc source while calculating output impedence

[@divasks8773]

because in ac analysis we have to short dc only
