Design a BiCMOS amplifier that is complementary to the one in Figure P13.50 in that the input devices are NMOS and the load transistors are pnp. Assume transistor parameters of \(V_{T N}=0.4 \mathrm{~V}, k_{n}^{\prime}=100 \mu \mathrm{A} / \mathrm{V}^{2}\), \(W / L=40, \lambda=0.02 \mathrm{~V}^{-1}, \beta=80\), and \(V_{A}=100 \mathrm{~V}\). Assume the bias current is \(I_{Q}=250 \mu \mathrm{A}\).

(a) Determine the small-signal parameters of the transistors.

(b) Find the small-signal differential voltage gain.
