Electronics textbooks will tell you that a non-inverting opamp normally cannot be regulated down to 0 dB gain. If zero output is needed then it is usual to employ an inverting amplifier and a buffer ...

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 ...

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 very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

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 ...

Use of buck-boost circuits in switching-regulator ICs. Considerations in level-shift circuit design. Switching regulators with internal level shifting. The magnitude of the negative voltage generated ...
