I am trying to use feedfoward compensation in multi-stage OTA for driving large capacitive load. However, it always oscillate, and PZ analysis in cadence spectre always shows RHP pole in my amplifier..
The circuit I have tried are all from journals. Here is one example https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=7389422
According to the journal's simulation it should not have any RHP pole.
Does anyone have the same experience?
Here is my amplifier
Here is my bode plot of amplifier
Here is its poles and zeros
