Consider the following current mirror combination, where all transistors have the same kn'(W/L) = kp'(W/L) = 2mA/V2, and VTN = 1V, VTP = -1V. It is also given that VDD1 = 10V, VDD2 = 8V. Remember that for saturation the drain current is given by ID = ½ kn'(W/L) (VGS – VTN)2 for NMOS and ID = ½ kp'(W/L) (VGS – VTP)2 for PMOS. You can ignore the channel modulation for all transistors.
