2.24 For an inverting amplifier with nominal closed-loop gain R2/R1, find the minimum value that the op-amp open-loop gain A must have (in terms of R2/R1) so that the gain error (due to the finite A) is limited to 0.1%, 1%, and 10%. In each case find the value of a resistor R Ia such that when it is placed in shunt with R 1, the gain is restored to its nominal value.
