The parameters for the transistor are VTN = 1 V, Kn = 3 mA/V, and Rs = 10 kΩ, RD = 5 kΩ, and RL = 4 kΩ. If the Q-point is IDo = 0.365 mA and Vpso = 4.53 V, a. Calculate the small-signal parameters, gm and ro. b. Sketch the small-signal equivalent circuit. c. Calculate the input resistance, Ri, to the amplifier.
