[@kamransalehi]

This was the best explanation of concepts. Make it easy for us. Thanks

[@coolwinder]

Professor, you lectures make these concept as lego peaces :)

[@mursalayub5167]

Thanks a lot sir .
HUGE CONTRIBUTION

[@DemosthenesKar]

I think 19:20 is gnd because its just A1 we a looking to find the open loop imp, K is just the connection that is removed

[@MrBubblegumx]

Why do we set the gate of M1 to GND at 19:20? That shouldnt be AC GND right?

[@binliu8375]

its ac gnd

[@SHan-wl6du]

@@binliu8375 could you explain why Gate of M1 is AC GND?

[@binliu8375]

@@SHan-wl6du actually it will be generally explained in lecture41.

@@binliu8375 Thank you :)

39:07 the ota is a bad op amp right it has very high output resistance

[@muratt6894]

Thank You

[@kiromaisus]

So good!!

legend , Thank you

8:15 why kA1 I don't get this part ?

[@許祐嘉-u1c]

KA1 is the Loop Gain.

[@rainbowrangers8148]

Last example had positive feedback or am i missing something ?

[@robertonania7331]

45:51 open loop output impedence of emitter follower is wrong because there is the effect of Rc of the second stage amplifier

[@shyavakbhuyan5743]

While finding the impedance of the follower, Vin will be set to 0 (being an independent voltage source), making Vout=0, hence, making one end of R1 ground, so there will not be any affect of Rc, making base resistance = R1 || R2.
