Read the Amplifier class notes.

For the amplifier circuit shown, R_S = 220 Ω, and R_L = 1.8 Ω.

For amp 1: R_i1 = 680 Ω, A₁= 20, R_o1 = 39 Ω.

For amp 2: R_i2 = 33 Ω, A₂= 5, R_o2 = 12 Ω.

For amp 3: R_i3 = 12 Ω, A₃= 5, R_o3 = 47 Ω.

For amp 4: R_i4 = 82 Ω, A₄= 15, R_o4 = 2.7 Ω.

Find the gain, G = v_o/v_i.
