Step of 4 11.030P Refer to the Figure 11.8(c) in the textbook. The feedback factor is, = Step 2 of 4 Expression of loop gain AB is considered from the Exercise 11.6 in the textbook. Open loop gain A is, AB Substitute for for in equation. = = Step 3 of 4 The closed loop gain is, A = = A, = (1) Step 4 of 4 Determine the resistor Substitute for A, for for for + in equation 1. 5 = (10k+1M)+4m(10kxR,) 5 = 5 = Further simplification as follows, = 200 =174.75x10³ Therefore, the resistance of resistor is
