Consider the circuit in Figure P10.26. Neglect base currents and assume \(V_{A}=\infty\). Assume \(I_{\mathrm{REF}}=100 \mu \mathrm{A}\) and \(R_{E}=700 \Omega\).

(a) For transistor parameters of \(I_{S 1}=I_{S 2}=5 \times 10^{-15} \mathrm{~A}\), find \(V_{B E 1}, V_{B E 2}\), and \(I_{O}\).

(b) Repeat part (a) if the transistor parameters are \(I_{S 1}=5 \times 10^{-15} \mathrm{~A}\) and \(I_{S 2}=\) \(2 \times 10^{-15} \mathrm{~A}\).
