Name: _________________ Problem 1 (15pts) For the PMOS amplifier shown below, assume V tp = -0.8V, K p W/L=3.5mA/V 2 . Neglect channel length modulation 2KΩ 2KΩ -2.5V 2.5V 0.35mA W/L 2W/L M1 M2 M3 M4 V x V G1 V G2 Vy Vd1 Vd2 (i)For V G1 = V G2 = 0V, Find the following voltages (V x , V y , V d1 , and V d2 ) V Y = V x = V d1 = V d2 = 2
Name _________________ (ii) What is the function of the two transistors (M3 and M4) (iii) If V G1 =V G2 =V in , what is the maximum value of V in after which the transistor M3 leaves its operating mode (changes from saturation to triode) 3
