Consider the diff-amp that was shown in Figure P11.63. The circuit and transistor parameters are \(V^{+}=2.8 \mathrm{~V}, V^{-}=-2.8 \mathrm{~V}, I_{Q}=120 \mu \mathrm{A}\), \(K_{n}=K_{p}=0.2 \mathrm{~mA} / \mathrm{V}^{2}, V_{T N}=+0.3 \mathrm{~V}, V_{T P}=-0.3 \mathrm{~V}\), and \(\lambda_{n}=\lambda_{p}=\) \(0.025 \mathrm{~V}^{-1}\).

(a) Determine the differential-mode voltage gain.

(b) What is the output resistance of the diff-amp?

(c) What is the maximum commonmode voltage that may be applied?
