Chapter 14, Problem 14.12P

Consider the two inverting amplifiers in cascade in Figure P14.12. The op−amp parameters are $A_{OL}=5\times {10}^3$ , $R_i=10\text{k}\Omega$ , and $R_o=1\text{k}\Omega$ . Determine the actual closed−loop gains $A_{\upsilon f1}={\upsilon }_{o1}/{\upsilon }_i$ and $A_{\upsilon f}={\upsilon }_{o2}/{\upsilon }_i$ . What isthe percent error from the ideal values?
