(a) If W1 is 1% higher than W2 in the foldedcascode op amp of fi nd the polarity and projected value of vO for vP 5 vN 5 0. Hence, fi nd the voltage vP that, with vN still at 0 V, will drive vO to zero (as we know, this is the input offset voltage VOS). (b) Repeat (a) if W7 is 1% higher than W8. (c) Repeat (a) if W5 is 1% higher than W6. (d) Repeat (a) if W3 is 1% higher than W4. (e) Repeat (a) if W9 is 1% higher than W10. (f) Compare all cases and comment.
