In the very first paper on feed-forward compensated opamp, https://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=1175504, the transfer function with capacitive feedback is given as having single zero whereas I'm getting one more RHP zero. What's the catch? Opamp in feedback and feed-fwd opamps are also attached along with transfer function.
