I watched this over 4 days and it was so much worth it. The intuitive techniques are a necessity when getting lost in long derivations and unable to interpret the results is a reality.
Dear Sir, thank you for sharing knowledge, and for the excellent method of delivery. Minor notice: From 2:58:16 onwards as you showcase the differential amplifier schematics; it is important to note that your output nodes' polarities should be reversed. Your diff pair devices are still common source amplifiers, so it stands to reason that the polarity of output node at D of device will be of opposite phase to input at G of device.
Knew almost all of the things taught in lecture but still it was very helpful to gain some new prospective on same concepts and learnt a lot from industry experience. Please share those notes used in lecture. thanks a lot.
Also, are you sure the expression you arrive at in 3:39:14 for the zero frequency is correct? Most analyses I've seen of the frequency response of the 5T OTA place the zero at ~ -2gm5/C2; i.e., twice the mirror pole frequency, *and at the LHP*, not RHP.
yes the common node doesnt see any "ac signal" or small signal, in other words even in AC or tran analysis it will remain in the same voltage(= the DC voltage) that you see in the operating point analysis
it is equal to 2von+vt only as the lower mos require 1 von=(vgs-vt) to be in saturation and the von+vt=vgs drop across vgs of upper mos total summing up to 2von+vt

so clearly explained about the effect of Electric fields on electron flow

thanks a lot.
Thanks a lot for this! Really helped me to revise my concepts!
great video! explain things so clearly!
Are you Chinese?
Great Efforts made......

great explanation . thank you sir.
thank you sir ,, i learned allot from you , i do really appreciate your sharing to the knowledge you have
Great work Sir.
AC ground gets created due to splitting of vin at 3:03:36, i didn't understand?

Thank you so much sir !! Really grateful sir !

In the 3rd topology of current mirror the gate voltage for upper MOS should be 2Vt+Von rather than 2Von+Vt.
it is equal to 2von+vt only as the lower mos require 1 von=(vgs-vt) to be in saturation and the von+vt=vgs drop across vgs of upper mos total summing up to 2von+vt
Thank you very much! I liked the notes is there any way i can get a copy of notes :O :D
Ty
can you please provide the pdf link for the reference . ? i mean hand written pdf .
