A the closed-loop gain of a feedback amplifier using an, Ask an Expert

Engineering

(a) The closed-loop gain of a feedback amplifier using an ideal feedback amplifier (A → ∞) is A_f = 125. What is the value of β?

(b) If the basic amplifier has a finite open-loop gain, what must be the value of A such that the closed-loop gain is within 0.25 percent of the ideal value. Use the results of part (a).
