The matched transistors \(Q_{1}\) and \(Q_{2}\) in Figure 10.2 (a) have parameters \(I_{S}=10^{-16} \mathrm{~A}\).

(a) For \(\beta=\infty\), determine \(I_{O}\) and \(V_{B E 1}\) for (i) \(I_{\mathrm{REF}}=50 \mu \mathrm{A}\), (ii) \(I_{\mathrm{REF}}=150 \mu \mathrm{A}\), and (iii) \(I_{\mathrm{REF}}=1.5 \mathrm{~mA}\).

(b) Repeat part (a) for \(\beta=50\).
