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 ...

Did you ever wonder how to calculate the stability of an op amp circuit? Put the wrong compensation network into the feedback loop, and you’re got an attenuator or, worse, an oscillator. It’s not ...

Modern op amps have much higher operating bandwidths than their predecessors. These new devices are excellent building blocks that can greatly simplify the design and construction of high-bandwidth ...

One of the biggest problems for designers of op-amp circuitry arises when the circuit must be operated from a single supply, rather than ± 15 V. This application note provides working circuit examples ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...

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 ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

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 ...
