Shown in Fig. P3.23 is a voltage divider implemented with two diode-connected nMOSFETs. Let both FETs have Vt 5 0.5 V, k

5 50 A/V2 ,  5 0, and 5 0. (a) If VDD 5 5 V, specify suitable WyL ratios for M1 and M2 so that the circuit gives V 5 2.5 V while drawing I 5 25 A from VDD. (b) Repeat, but for V 5 1.5 V and I 5 10 A. (c) If (WyL)1 5 (1 m)y(1 m), specify (WyL)2 so that V 5 3 V; let the smaller of W and L in (WyL)2 be 1 m. What is the power dissipated by the circuit? Hint: use the fact that ID1 5 ID2.
