Assume the transistor in the circuit in Figure P6.16 has parameters \(\beta=120\) and \(V_{A}=100 \mathrm{~V}\).

(a) Design a bias-stable circuit such that \(V_{C E Q}=5.20 \mathrm{~V}\).

(b) Determine the small-signal transresistance function \(R_{m}=v_{o} / i_{s}\).

(c) Using the results of part (a), determine the variation in \(R_{m}\) if \(100 \leq \beta \leq 150\).
