Cascade Current Mirror - Analog Circuit Design Interview 

Good explanation

the explanation is misleading in a different way. not the exact answer

@ 4.56 --> The MOS goes into Linear ( I have recorded as saturation though 😃 ) Make a note please

Can we say when both mos are in saturation intially, (Ids vs Vds) curve for both Mos overlap ??

great explanation. Thanks a lot.

😃M2 was the cascode device, which acts as a sheild. The voltage of M2 source change very little when its darin changes.( all in saturation)

This problem and explanation are good.. Thank you very much ..
