In my previous article on common op-amp circuits, I mentioned that operational amplifiers were used for analog computing, where analog circuits simulated the behavior of complex systems. That article ...

The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...

After a brief review of the history of the K2-W vacuum-tube op amp, an LTspice model is used to create its schematic in preparation for SPICE simulation. The availability of hierarchical blocks for ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...
