Question:

Consider the circuit in Figure P10.43. The transistor parameters are: $\beta=\infty, V_{A}=\infty$, and $V_{B E}=0.7 \mathrm{~V}$. Design the circuit such that the B-E voltages of $Q_{1}, Q_{2}$, and $Q_{3}$ are identical to that of $Q_{R}$. What are the values of $I_{O 1}, I_{O 2}$, and $I_{O 3}$ ?
