Repeat Problem 11.78 if \(I_{Q}=120 \mu \mathrm{A}, V_{A N}=75 \mathrm{~V}\), and \(V_{A P}=40 \mathrm{~V}\). All other parameters remain the same.

Data From Problem 11.78:-

The circuit and transistor parameters of the bipolar diff-amp shown in Figure P11.78 are \(I_{Q}=200 \mu \mathrm{A}, \beta_{\text {npn }}=125, \beta_{\text {pnp }}=80, V_{B E}(\) on \()=\) \(V_{E B}(\) on \()=0.7 \mathrm{~V}, V_{A N}=100 \mathrm{~V}\), and \(V_{A P}=60 \mathrm{~V}\).

(a) What are the minimum power supply voltages (assume symmetrical supply voltages) if the common-mode input voltage is to be in the range of \(\pm 2 \mathrm{~V}\).

(b) What is the differential-mode voltage gain?
