Non-Inverting Op-amp Amplifier

Several months ago I introduced op-amps to readers of this site with “The Non-Inverting Op-Amp Amplifier“. At that time we had only talked about D.C. Electricity. We started with an “ideal Op-Amp” and then I brought us back to reality and created a video about an op-amp datasheet. Since that time

Bode Plots – Phase Margin and Gain Margin

Feedback Header

Generic Feedback Block Diagram

Sometimes it is very hard to not get “the horse ahead of the cart”. Very often in projects and design as well as learning multiple things must be accomplished at the same time, yet one of those laws of nature is matter can only be at one place at one

The importance of Phase in the frequency plots.

The Lowpass filter for this discussion.

We have been talking about the phase shift when creating frequency plots, but it has not been given a lot of importance. Other than power-factor it really has not affected us that much. We have been mostly interested in the gain plot. That is just about to change.
