Question

A feedback op-amp circuit is shown in the figure below. In the circuit, ( R_{s}=2 k Omega, R_{1}=10 k Omega, R_{2}=10 k Omega, R_{3}=5 k Omega ), and ( R_{L}=2 k Omega ) Part 1: The op-amp is non-ideal with an internal input resistance ( r_{i}=200 mathrm{k} Omega ), an internal output resistance ( r_{o}=200 Omega ), and an internal gain ( A_{v o}=20 frac{k V}{V} ). Apply the systematic analysis method. (1) What is the feedback topology of the circuit? (2 marks) (2) Calculate the feedback factor ( beta ). (2 marks) (3) Calculate the open-loop gain ( A ) of the circuit. (5 marks)
