Problem 2: Consider the following NMOS inverter. Assume that the input IN has a 0 V to 2.5 V swing. Assume VT0 = (0.43 + X/100)V, where X is the last digit of your ID. Ignore channel length modulation. Ignore body effects. a) Find the voltage on node x. b) What is the range for VOUT as IN varies from 0 to 2.5. What is the mode of operation of M2 over that range. Use long channel regions to get a good guess?
