2. (10) The op-amp A in the following circuit can be considered ideal except that it has a finite open-loop gain of 4 - 66.02 dB. 1) (1) Identify the topology of the feedback. 2) (1) Find the feedback network of the circuit and the feedback gain as a function of R, and R. 3) (2) Prove that the feedback is negative. 4) (4) If R; = 2.0 k1, design Rso that an exact Ar=20.0 V/V can be achieved. 5) (2) In step d). if A has a variation of 8.4%, estimate the corresponding variation of Ay in percentage. + V A Vo R1 R2 HB
