Question:

For the transistors in the circuit in Figure P11.5, the parameters are \(\beta=100\) and \(V_{B E}(\mathrm{on})=0.7 \mathrm{~V}\). The Early voltage is \(V_{A}=\infty\) for \(Q_{1}\) and \(Q_{2}\), and is \(V_{A}=50 \mathrm{~V}\) for \(Q_{3}\) and \(Q_{4}\).

(a) Design resistor values such that \(I_{3}=400 \mu \mathrm{A}\) and \(V_{C E 1}=V_{C E 2}=10 \mathrm{~V}\).

(b) Find \(A_{d}, A_{c m}\), and \(\mathrm{CMRR}_{\mathrm{dB}}\) for a one-sided output at \(v_{O 2}\).

(c) Determine the differential- and common-mode input resistances.
