Problem 52: (25 points) Operational amplifiers are important building blocks in a wide spectrum of electronic systems such as amplifiers and filters. The concept of feedback control is of central importance in understanding the design of operational amplifier circuits. For without feedback, operational amplifiers behave as comparators. This problem shows why it is necessary to connect the output of an operational amplifier to its inverting input. Negative feedback produces a circuit that is BIBO stable. Figure 1(A) shows the circuit...
