Repeat Problem 4.12, but now assuming that 2-k„¦ resistors are inserted in series with the emitters of Q₃and Q₄.

Repeat Problem 4.12:

Determine the unloaded voltage gain ν_o/ν_i and output resistance for the circuit of Fig. 4.58. Check with SPICE and also use SPICE to plot out the large-signal V_O-V_I transfer characteristic for V_SUP = 2.5 V. Use SPICE to determine the CMRR if the current-source output resistance is 1 M„¦.
