Feed-forward compensated opamp (Read 3022 times)

leon_O New Member Offline Posts: 6 Chennai	Feed-forward compensated opamp May 15^th, 2014, 12:31am In the very first paper on feed-forward compensated opamp, http://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? Attached is the transfer function given in the paper.
