Question:

Repeat Problem 3.27 but with matched loads and mismatched transistor output resistances. Assume R₁ = R₂ = 10 kΩ, r_o1 = 505 kΩ, and r_o2 = 495 kΩ. What happens when r_tail → ∞?

Data from Prob. 3.27:

Use half-circuit analysis to determine A_dm, A_cm, A_cm−dm, and A_dm−cm for a resistively loaded differential pair with mismatched resistive loads, R₁ and R₂. Assume that R₁= 10.1 kΩ and R₂ = 9.9 kΩ. Also assume that g_m1 = g_m2 = 1 mA/V, r_o1 → ∞, and r_o2 → ∞. Finally, assume that the equivalent resistance of the tail current source r_tail =1 MΩ.
