Consider the Widlar current source in Figure 10.9, with parameters given in Example 10.5. Choose appropriate transistor parameters. Connect a \(50 \mathrm{k} \Omega\) resistor between \(V^{+}\)and the collector of \(Q_{2}\) as a load. Using a computer simulation, determine \(I_{\mathrm{REF}}, I_{O}, V_{B E 1}\), and \(V_{B E 2}\).
