Fig. 3 I. If Vx = 0 V, what logic function is implemented? II. What is VOL if Vx = 0 V? III. Is VOH = VDD if Vx = 0 V? Briefly explain your answer. IV. If Vx = 0 V, write an expression for the gate switching threshold, Vm. What is the region of operation of M1? What is the region of operation of M2? V. How can this circuit be modified to maximize the output voltage swing (i.e., get VOH close to VDD and VOL close to ground)? Explain briefly.
