The enhancement-type PMOS transistors Q1 and Q2 in the circuit below are characterized by ⎛W ⎞ the following parameters: k p' ⎜ ⎟ = 4 mA/V2, Vt = −1 V, VA= ∞. Find ID, VSD, and the ⎝L⎠ operating mode for both transistors. (6 points) VGS1 = VDS1 ∴Saturation VGS2 = VDS2 ∴Saturation ID1 = ID2 = ID, then VGS1 = VGS2 and VDS1 = VDS2 = VDS 2VSD = 3 V or VSD = VSD1 = VSD2 = 1.5 V ID = (1/2)kp’(W/L)(VGS - Vt )2 = (2 mA/V2)[-1.5 V - (-1 V)]2 = 0.5 mA -2- ⎛W ...
