Common-Source Amplifier (30 points) Calculate the Q-point, the terminal voltage gain A vt , the signal source voltage gain A v , the input resistance R in and the output resistance R out of the common-source amplifier shown on the right. Assume R I = 1 k , R 1 = R 2 = 2.2 M , R S = 22 k , R D = 18 k , R 3 = 470 k , K p = 400 A/V 2 , V T = 1 V, = 0.02 V-1 , V DD = 18 V. 4. SPICE Simulation (20 points) Find the Q-point and the signal source voltage gain A v of the amplifier given in problem 3 using SPICE. Please provide a plot of the circuit showing the dc currents and voltages and a plot showing the input and the output signal at 7.5 kHz as a function of time. Assume, C 1 = C 2 = C 3 = 10 F....
