Unformatted text preview: (30 points) 3. MOSFET: I-V Characteristic (20 points) The output characteristic for an NMOS transistor (I D vs V DS for different V GS ) is given in the graph on the right. What are the values for K’ n W/L and V TN for this transistor? 4. MOSFET: Q-Point Analysis (30 points) Find the Q-point for the transistor (a PMOS transistor) on the right. Assume that V TP = –1 V, W/L = 1/1 and K p ’ = 25 μA/V 2 ....
