The circuit and transistor parameters for the ac equivalent circuit in Figure P6.43 are \(R_{S}=0.5 \mathrm{k} \Omega, \beta=120\), and \(V_{A}=\infty\).

(a) Determine the required value of \(I_{Q}\) to produce a small-signal output resistance of \(R_{o}=15 \Omega\).

(b) Using the results of part (a), find the small-signal voltage gain if \(V_{A}=50 \mathrm{~V}\).
