2. For the circuit shown in Figure 2, the transistor parameters of Q₁ and Q₂ are: = 1.2 V, W/L = 1.6 mA/V², and neglect channel length modulation effect. Let R₁ + R₂ + R₃ = 300 kΩ and = 10 kΩ. = 5 V, - = -5 V.

(a) Please determine the R₁, R₂, R₃ and such that DC current = 0.4 mA and DC voltage = 2.5 V.
