Hey Everyone,
I’m having trouble understanding the basic analogy of op amp feedback networks. Due to my diminutive understanding of op amps, I can’t apply the math to analyze and apply the necessary output equations, and equations in general.
To edify myself in that regard, I thought it would be best if someone defined op amp feedback to begin with. I assume it is different than the feedback from a microphone and speaker via an audio amp?
Consider the following link and go to page 78-79 (Figure 5-6):
https://www.electro-tech-online.com/custompdfs/2010/04/slod006b.pdf
It might help to depict box diagrams that explain the feedback methods like in the link, but those equations I don’t entirely understand.
Next, I’m hoping that several of you can provide several visionary examples (in other words, schematics) that will elucidate the primary meaning of feedback, and how I can apply the equations based on resistor networks (start out with just resistors, no caps, inductors, etc.)?
Finally, I wanted to ask what most op amp designers need to know while designing various projects; what methods do you use the most? What do you need to know in order to perform those methods and equations?
I am exceedingly anxious to start designing multifarious projects with op amps, and I would appreciate any help that people have to offer!
Thanks,
Austin
