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 νo/νi and output resistance for the circuit of Fig. 4.58. Check with SPICE and also use SPICE to plot out the large-signal VO-VI transfer characteristic for VSUP = 2.5 V. Use SPICE to determine the CMRR if the current-source output resistance is 1 M„¦.

Figure 4.58:

+VSUP Q3 v,= Vo+v Q2 V = V, + v; 100 μΑ -VSUP
