Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having … ...

In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

The operational amplifier (op-amp) is a high performance gain device with essentially linear qualities.

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 op-amp circuit in question. He starts with the current source, a simple circuit of two diodes, a resistor, and a transistor that sets the bias for the two-transistor differential amplifier.

For continuous-duty, high-amperage circuits Hamilton prefers to use ring terminals rather than spade connectors, since they offer a superior connection with less chance of failure.

Various techniques can reduce these errors, including inverted operating mode, dc biasing, small ac signal swing, proper selection of the op amp, and input impedance compensation.1 Matching the ...

Do you have enough amperage capacity in the service panel for a new 240-volt appliance? Service panels are rated for the maximum amps they can provide.
