We are all used to the op-amp, as a little black box from which we can derive an astonishingly useful range of circuit functions. But of course within it lurks a transistor circuit on a chip, and ...

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 Splitvolt splitter switch allows EV owners to safely charge their car from an existing 240-volt outlet in their home. This can save them anywhere from a few hundred dollars to thousands. By ...
