Hello nrk1 and RobG. Thank you for your replies.
RobG, could you explain why the added capacitors not form feedback path around the opamp? Also as I mentioned in the first post, adding the capacitors between the input and output terminals of the opamp, in such a way that positive feedback is realized, does not show unstable behavior when excited with a step.
nrk1, the gain between the input and the cascode nodes is not less than 1 and is shown in the post 3, in the same thread. Also isn't having a single RHP pole sufficient to make the system unstable? The output pole due to the load capacitor might be in LHP, but would the system be stable if the pole formed due to the added capacitor between gate and the cascode node ends up being in RHP?
Thank you all once again.
