Verify the operations of current mirror circuit by LTSpice simulation. 5.1 (5 point) Create the following MOSFET current mirrow schematic, assigning the parameters and label the X and Y nodes (Hints: For M1, you need to "mirror" NMOS4). For M1 and M2: kn = 200 u vT0 = 0.5 W1 = W2 = 50 u L1 = L2 = 10 u IREF = 50 uA VDD = 5 V
