Understand the basics of op amps and their applications in circuit design. Learn how these devices function.

It is shown that two of the recently reported voltage mode and current mode current conveyor-based all-pass circuits can be generated from the well known single input op amp all-pass configuration. It ...

Whether this timeless effect comes from an amp or a pedal, the sound of this O.G. guitar effect still has us shaking all over ...

Our project creates a versatile function generator using op-amps to generate sine, square, and triangular waveforms. Additionally, it doubles as an electrocardiogram (ECG) signal amplifier for medical ...

Circuit: Op-Amp Tester Want to repurpose an operational amplifier from a previous project or an old parts collection? Be careful: its functionality might be compromised. Testing an op-amp with a ...

To allow the comparison of different op-amps in a headphone amplifier, [Stephan Martin] has created a stereo amplifier board complete with sockets to take single or dual op-amp chips.

Here is a comparison between discrete transistor-based solution and op-amp-based LED current balancing circuit used in multiple LED strings.

There are two types of feedback, positive feedback and negative feedback in op-amp circuits, both of which are covered in this article in detail.
