Operational Amplifiers
1010602Operational AmplifiersTransistors are the basic building blocks of solid-state amplifiers. Designing an amplifier using discrete transistors can be a substantial undertaking that requires theory outside the scope of this book. Operational amplifiers, or op-amps, exist to make the design of basic amplification circuits relatively easy. A digital engineer can use an op-amp to construct a general-purpose amplifier or active filter to preprocess an analog signal that may serve as input to the system. Comparators, which are based on op-amps, are useful in triggering events based on a signal reaching …
