*D10.43 Consider the circuit in Figure P10.43. The transistor parameters are:
$\beta$ = $\infty$, $V_A$ = $\infty$, and $V_{BE}$ = 0.7 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 $I_{O1}$, $I_{O2}$, and $I_{O3}$?
$V^+$ = 10 V
$I_{REF}$
$R_1$ = 6.3 k$\Omega$
$I_{O1}$ $I_{O2}$ $I_{O3}$
$Q_R$
$Q_1$ $Q_2$ $Q_3$
$R_{ER}$ = 3 k$\Omega$
$R_{E1}$ $R_{E2}$ $R_{E3}$
