Funny thing - I have not used pole splitting in many years.
I use a source follower to drive the feedback capacitor, which provides feedback while getting rid of the HF feedforward path. (No resistor anymore in the feedback path that way)
Also, for best swing, outputs are OTA, class AB, so that you can get rail to rail output.
Just my approach, others are viable, but the above has served well for me.
i.e. Ahuja compensation. Yes! that's a good way to do it. However, I think the classical Miller compensation scheme is not so bad. At the very least, one is forced to confront all these nasty design issues

I actually cannot think of another example circuit which is so popular, yet so poorly understood and so full of traps lurking everywhere.
