Consider the pnp current source in Figure P10.13, with transistor parameters \(\beta=\infty, V_{A}=\infty\), and \(V_{E B}\) (on) \(=0.7 \mathrm{~V}\).

(a) Design the circuit such that \(I_{\mathrm{REF}}=1 \mathrm{~mA}\).

(b) What is the value of \(I_{O}\) ?

(c) What is the maximum value of \(R_{C 2}\) such that \(Q_{2}\) remains biased in the forward-active mode?
