The diff-amp in Figure P11.63 is biased at \(I_{Q}=0.5 \mathrm{~mA}\). The transistor parameters are \(K_{n}=K_{p}=0.25 \mathrm{~mA} / \mathrm{V}^{2}, V_{T N}=0.4 \mathrm{~V}, V_{T P}=-0.4 \mathrm{~V}\), and \(\lambda_{n}=\lambda_{p}=0.02 \mathrm{~V}^{-1}\).

(a) What are the minimum power supply voltages if the common-mode input voltage is to be in the range \(\pm 3 \mathrm{~V}\) ? Assume symmetrical supply voltages.

(b) Determine the differential-mode voltage gain.
