Consider the common-source amplier shown in Figure. The NMOS transistor has KP = 50 A/V2, L = 5 m, W = 500 m, Vto = 1 V, and rd = ∞.
a. Determine the values of IDQ, VDSQ, and gm.
b. Compute the voltage gain, input resistance, and output resistance, assuming that the coupling capacitors are short circuits for the ac signal.
