Prof Ali ...Thank you very much for uploading your lecture to help guys like me to learn from one of the best analogue/RF designer.

If I may to draw your attention that, this the last lecture I can watch on YouTube?

Thank you for your help, May Allah give you all the best!

in 4:32 if the horizontal axes represents digital numbers, then half LSB does not exists.
in 13:38 because we are considering the analog signal, I think that It has to settle under delta/2 = Vref / (2^ (N+1)), and not LSB/2

stefano.a

With Delta R, the equation assumes that each resistor in the ladder deviates by the exact same amount (of Delta R) ... the error of each resistor's resistance are "matched". In *actual* voltage, shouldn't Delta R be different for every resistor?

I enjoy these lectures, dear Prof., but you didn't seem to be so sharp today. I think you confused yourself in several places. But we all have days like that ;-)

Hi sir its very nice class...Sir can you please do some problems related to this topic ie, how to find out DNL and INL.I have some problems but felt difficulties to solve that ..so please help me out sir
