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 ...

The Current Feedback Amplifier (CFA) burst onto the scene in the mid-1980s with the commercialization of this new topology by Comlinear Corporation. It quickly propagated industrywide with many ...

Negative feedback is used in voltage regulators, point-of-load (POL) regulators, voltage references, operational amplifiers (op-amps), and other electronic circuits in order to produce an accurate ...

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 ...

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 ...

The stability of high-unity-gain-bandwidth op amps is susceptible to stray capacitances. Instability doesn't first show up as oscillation, but rather pronounced overshoot and ringing. Op amps such as ...
