= DD 3.25 In the voltage divider of Fig. P3.23 both FETs have V, = 0.5 V, k' = 50 MA/V?, y = 0, and = 0. (a) If Vpp = 3 V, and the W/L ratio for each de- / vice is constrained within the range (1 um)/ (10 um) = W/L = (10 um)/(1 um), what is the possible range of values for V? What is the current drawn by the circuit from Vpp? (6) Specify W/L ratios for the two devices such that the circuit yields V - Vpp/2 while draw- ing the same current as it does at the extremes of part (a); let the smaller of Wand L be 1 um. (c) What happens if Vpp is doubled to 6 V? Comment on your findings. Hint: use the fact that loi = 102 2 DI D2
