Question

The parameters of the transistors in the circuit in Figure are β_F ≡ β = 25 and β_R = 0.1.

(a) Determine the values of i₁, i₂, i₃, v₁, and v_O for (i) vI = 0.1 V and (ii) vI = 2.5 V.

(b) Determine the values of vI and v₁ at the point (i) where Q₀ just begins to conduct and (ii) where Q₀ just goes into saturation.
