For the common-gate amplifier below is operating with gm = 0.6 mS, RI = 50 Ω, R4 = 3 kΩ, and RL = 82 kΩ : a) Draw the AC equivalent circuit with the small signal model for the transistor. b) Calculate the voltage gain, Av. Neglect r0. c) Draw the circuit to find the amplifier input resistance ( Rin). d) Calculate Rin. e) Draw the circuit to find the amplifier output resistance ( Rout ). (Hint: since Q = point is unknown assume λ = 0). f) Calculate Rout.
