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 ...

(If this op amp were operated in a buffer configuration, it would have a phase margin of 43 degrees.) If the op amp were used in an inverting configuration with a gain of one, K would be 0.5 or -6dB ...

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 res… ...

This very sturdy-looking circuit provides an easy way to configure the op-amp for testing in inverting, non-inverting, and transimpedance mode, selecting from a range of feedback resistors, and ...

For inverting amplifiers, a fixed voltage divider fed the pot. Obviously, if the K2-W's V os stayed inside 50 mV after you trimmed it, that's comparable to a ±10-V op amp keeping its V os inside ...
