You are doing a great work man👍Would be very nice if you could bring 1) questions involving opamps with both positive and negative feedbacks 2) Compensation in opamps 3) Identifying opamp signs 4) More interview questions on Mosfet single stage amplifiers 5) Interview questions on Barkhausen Criteria 6) Graphical questions on Vo vs Vi for mos amplifiers

Sir in case of square pulse wave of magnitude 5v, the output voltage would be saturated but the capacitor voltage would be oscillating between 5+Vsat , and +Vsat, whereas the avarage value of current through the cap should be zero at the steady state. Please sir correct me if i am wrong. Thank yu for making such wonderful contents.

Nice one bro, can you make a similar video on differentiator. The confusion with differentiator 1)If i assume the opamp is in negative feedback for all Freq. -then at the instance of step, all step voltage will appear across cap, since other node is held at 0 potential due to virtual gnd - therefore there is a impluse current set through cap - therefore my output will be a negative impulse 2) but if i consider the actual case, that is no feedback at high freq ( since loop gain of this ckt at high freq is 0) - at the moment of step the cap will short - virtual short concept fails - no current in feedback path, since no feed back at high freq - therefore vo is vi What shld i consider,Plz clarify

I have made a video over it. Please find it in Prep for Interview series

So we can’t apply virtual ground concept in those scenarios because it’s not acting as amplifier anymore is that right ?
