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 ...

Last month we explored noise of the non-inverting amplifier but I dodged the issue of the feedback network’s noise contribution. A reader, Jim, challenged me—he wanted more detail. So what about the ...

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 ...

This file type includes high-resolution graphics and schematics when applicable. Most data-acquisition systems with wide dynamic range need a method of adjusting the input-signal level to the ...

In some applications, a linear amplifier is required which has different gains with regard to the polarity of the input signal. Figure 1 shows an inverting amplifier which is linear within the second ...
