Consider the bipolar op-amp configuration in Figure 11.49. The bias voltages are \(\pm 10 \mathrm{~V}\), as shown, the current \(I_{R 7}\) is to be \(I_{R 7}=3 \mathrm{~mA}\), and the maximum dc power dissipation in the circuit is to be \(120 \mathrm{~mW}\). The output voltage is to be \(v_{o}=0\) for \(v_{1}=v_{2}=0\). Design the circuit, using reasonable resistance and current values. What is the overall differential-mode voltage gain?
