The bias currents in the circuit shown in Figure P11.89 are \(I_{1}=0.25 \mathrm{~mA}\) and \(I_{2}=1.0 \mathrm{~mA}\). The transistor parameters are \(K_{n}=0.5 \mathrm{~mA} / \mathrm{V}^{2}\), \(K_{p}=1.0 \mathrm{~mA} / \mathrm{V}^{2}, V_{T N}=0.8 \mathrm{~V}, V_{T P}=-0.8 \mathrm{~V}\), and \(\lambda_{n}=\lambda_{p}=0.02 \mathrm{~V}^{-1}\).

(a) Determine the resistor values \(R_{1}\) and \(R_{2}\) such that the dc value of the output voltage is zero.

(b) Sketch the small-signal equivalent circuit and find the small-signal transistor parameters.

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

(d) Determine the output resistance \(R_{o}\).
