Consider the circuit in Figure P11.57. Assume that \(\lambda=0\) for the transistors, and assume an ideal current source \(I_{Q}\). Derive the expressions for the one-sided differential-mode gains \(A_{d 1}=v_{o 1} / v_{d}\) and \(A_{d 2}=v_{o 2} / v_{d}\), and for the two-sided differential-mode gain \(A_{d}=\left(v_{o 2}-v_{o 1}\right) / v_{d}\).
