Fixed capitalisation. Op-amp is short for "operational amplifier". It's not an initialisation.

OP Op-AMP Controlamp control theory

back at it again trying to use your genius brains.

I have been trying to teach myself Audioaudio amplifier design. The big road block I am getting into is the control theory part of it, meaning how does the feedback loop affect the OPop-AMPamp characteristics such as adding a zobelZobel network, or a capacitor compensation in the feedback.

I would love to understand and workout the math of how to model OPop-AMPamp and understand how the poles and zeroes are.

For example here is what I have been working with: 

enter image description here

How do I approach this trying to figure out the feedback loop transfer function?

Do I assume in DC or AC? or do I need miller capacitance model.

My end goal is trying to figure out how does the Zobel Networknetwork and other things affect the performance of the audio op amp. :)

Cheers.
