Consider the two inverting amplifiers in cascade in Figure P14.12. The opamp parameters are \(A_{O L}=5 \times 10^{3}, R_{i}=10 \mathrm{k} \Omega\), and \(R_{o}=1 \mathrm{k} \Omega\). Determine the actual closed-loop gains \(A_{v f 1}=v_{o 1} / v_{i}\) and \(A_{v f}=v_{o 2} / v_{i}\). What is the percent error from the ideal values?
