Many applications require a sampling circuit whose output is inverted with regard to the respective sample of an input signal. A simple approach is a cascade of a common noninverting sample-and-hold ...

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 ...

There is an occasional caution that even unity-gain stable Voltage Feedback Amplifiers (VFAs) risk instability in inverting attenuator applications (Reference 1). In fact, there should be no more ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally, at least — it ...

Op-amps are among the most widely used electronic devices, and are designed into many consumer, industrial, and scientific devices. General purpose, standard op amps sell for well under one dollar.

Engineers are frequently faced with the challenge of developing applications to meet a wide range of requirements. Usually, these requirements are difficult to fulfil simultaneously. One example is ...

Industrial and medical design continually push to improve product accuracy and speed. The analogue integrated circuit industry has generally keptup with speed requirements, but it is falling behind on ...

What if a palm-sized amp could outperform larger, more expensive modules while delivering serious sound quality? Check out this 60-W amplifier design.
