In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

Op amps excel at providing many useful and clever solutions to routine or complicated circuit functions. A summing circuit is a perfect example. A summing circuit is typically used in applications ...

Operational amplifiers (commonly called op amps) are a ubiquitous building block for designing electronic circuits. Today, these devices are fabricated as small integrated circuits, but the concept ...

The comparator demonstrates the ``open-loop'' behavior of an op amp. You can design the reference voltage so that the output voltage will ``switch'' whenever the input voltage (at the inverting input ...

Operational amplifiers are a valuable component for designers. There are many different types of circuits that can be designed using op amps. Designers may not be aware of all of the possible ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...
