Reconsider the circuit in Figure P11.60 except that \(1 \mathrm{k} \Omega\) resistors are inserted at the emitters of the active load transistors \(Q_{3}\) and \(Q_{4}\) as in the circuit in Figure P11.66. Assume the same transistor parameters as in Problem 11.60.

(a) Determine the output resistance looking into the output of the diff-amp circuit.

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