In the course of the dc analysis of the input stage of the 741 op amp, repeated in Fig. P7.35 for convenience, it was stated that the biasing scheme adopted utilizes negative feedback. Assuming Fp 5 50 and very large Fn, fi nd T. Hint: break the loop at pint X, inject a test current it into Q8, and fi nd the amount of current ir returned by the Q1-Q2 pair.
