Please solve it clearly and by steps
8.1 For an NMOS differential pair with a common-mode voltage Vay applied, as shownin Fig. 8.2, let VppV 1.0 V k, = 0.4 mA/V2. (WIL),.-10·V, 0.4 V, 1-0. 16 mA. R 5 k2, and neglect channel-length modulation. (a) Find Vov and Vos for each transistor. (b) For Vo 0, find V, lp Ip, Vo, and V (c) Repeat (b) for Vcu+0.4 V (d) Repeat (b) for Vc-0.1 V. (e) What is the highest value of Va for which and Q remain in saturation? If current source I requires a minimum voltage of 0.2 V to operate properly, what is the lowest value allowed for V, and hence for Vu? (f)
