Consider the circuit shown in Figure P6.76 with transistor parameters \(\beta=120\) and \(V_{A}=\infty\).

(a) Determine the small-signal parameters \(g_{m}, r_{\pi}\), and \(r_{o}\) for both transistors.

(b) Plot the dc and ac load lines for both transistors.

(c) Determine the overall small-signal voltage gain \(A_{v}=v_{o} / v_{s}\).

(d) Determine the input resistance \(R_{i s}\) and the output resistance \(R_{o}\).

(e) Determine the maximum undistorted swing in the output voltage.
