Question

The circuit configuration shown in Figure is redesigned such that V_CC = 3.3 V, R₁ = 16 k, R_C = 6 k, and R_B = 20 k. Let β = 50.

(a) Determine i₁, i₃, i₄, and v for (i) v_X = 0.1 V, v_Y = 3.3 V and (ii) v_X = v_Y = 3.3 V.

(b) Calculate the maximum fanout for the output low condition such that Q₁ remains biased in saturation.

(c) Repeat part (b) if the maximum collector current is limited to 5 mA.
