Let lambda 002 v-1 for m10 if the transistor bias currents

Question

Assume the gain stage of the CA3140 op-amp is modified to include an emitter resistor, as shown in Figure 13.23. Let λ = 0.02 V^-1 for M_10. If the transistor bias currents in M₁₀ and Q₁₂ are 150 μA and the current in Q₁₃ is 300 μA, determine the dominant-pole frequency and unity-gain bandwidth.
