In the voltage divider of both FETs have Vt 5 0.5 V, k 5 50 A/V2 , 5 0, and 5 0.

(a) If VDD 5 3 V, and the WyL ratio for each device is constrained within the range (1 m)y (10 m) # WyL # (10 m)y(1 m), what is the possible range of values for V? What is the current drawn by the circuit from VDD?

(b) Specify WyL ratios for the two devices such that the circuit yields V 5 VDDy2 while drawing the same current as it does at the extremes of part (a); let the smaller of W and L be 1 m.

(c) What happens if VDD is doubled to 6 V? Comment on your fi ndings. Hint: use the fact that ID1 5 ID2.
