In the circuit in Figure P10.84, the active load circuit is replaced by a Wilson current source. Assume that \(\beta=80\) for all transistors, and that \(V_{A N}=120 \mathrm{~V}, V_{A P}=80 \mathrm{~V}\), and \(I_{\mathrm{REF}}=0.2 \mathrm{~mA}\). Determine the opencircuit small-signal voltage gain.
