Hi buddypoor,
Thanks for your reference. It seems good to produce a zero by VCCS instead of esr resistor.

Hi trashbox,
I know that the paper I have posted is not complete.
Therefore I like to add the information, that - as a final conclusion - the paper did propose to place a capacitor across R2 in order to produce a zero in the frequency response of the loop gain.

Hi buddypoor,
What do you mean it is not completed?

My simulation shows it can produce a zero as the paper described though there is some magnitude peaking in frequency response,and these peaking is far away from the poles and zero.

The text ends abruptly - with other words: the last part of the paper is missing. This is what I ment with "not complete".
