Chapter 13, Problem 13.57(choose chapter or problem)
Consider the circuit of Fig. 13.14 modified to include resistors R in series with the emitters of each of Q8 and Q9. What does the resistance looking into the collector of Q9, Ro9, become? For what value of R does it equal Ro10 (i.e., 31.1 M)? For this case, what does Ro looking to the left of node Y become? (Recall that Q9 is biased at 0.73 mA.)
