Design a differential amplifier with the configuration shown in Figure 11.28 incorporating a basic two-transistor current source to establish \(I_{Q}\). The bias voltages are to be \(V^{+}=+5 \mathrm{~V}\) and \(V^{-}=-5 \mathrm{~V}\), the bias current is to be \(I_{Q}=250 \mu \mathrm{A}\), and the available transistors have parameters \(\beta=180\), \(V_{B E}(\) on \()=V_{E B}(\) on \()=0.7 \mathrm{~V}, V_{A N}=150 \mathrm{~V}\), and \(V_{A P}=100 \mathrm{~V}\).

(a) Show the complete circuit.

(b) What is the open-circuit differential-mode voltage gain.

(c) Determine the differential-mode input resistance and the output resistance.

(d) Determine the common-mode input voltage range.
