2.26 Figure P2.26 shows an op amp that is ideal except for having a finite open-loop gain and is used to realize an inverting amplifier whose gain has a nominal magnitude G = R2/R1. To compensate for the gain reduction due to the finite A, a resistor Rc is shunted across R1. Show that perfect compensation is achieved when Rc is selected according to
