Suppose that because of some design error the folded-cascode op amp of is fabricated with W9 5 W10 5 24 m instead of 40 m. (a) Assuming Cc 5 2.5 pF, discuss how this error affects a0, fb, and ft , compare with and comment. (b) Find all drain currents during positive SR limiting (vP @ vN), compare with Exercise 6.6b. (c) Repeat (b), but for negative SR limiting (vP ! vN), and compare. (d) Discuss the main functional difference between the correct and the erroneous circuit.
