Consider the differential amplifier shown in Figure P11.41 with mismatched drain resistors. The circuit and transistor parameters are \(V^{+}=\) \(+10 \mathrm{~V}, V^{-}=-10 \mathrm{~V}, R_{D}=50 \mathrm{k} \Omega, R_{S}=75 \mathrm{k} \Omega, V_{T N}=1 \mathrm{~V}, K_{n}=\) \(0.15 \mathrm{~mA} / \mathrm{V}^{2}\), and \(\lambda=0\). Determine \(A_{d}, A_{c m}\), and \(\mathrm{CMRR}_{\mathrm{dB}}\) for \(\Delta R=\) \(500 \Omega\) and for \(v_{O}=v_{D 1}-v_{D 2}\). Assume \(v_{1}=v_{2}=0\) in the quiescent condition.
