Is there a spice model of the PSoC4 opamp or maybe a component that is very similar to it?
It would help to estimate phase margin when using the internal amplifiers for my project.
There is no official spice model available for the components. But kindly check the component parameters in the device datasheet. The CTBm pins to which are connected to Opamps have different input leakage current , which can be derived into the input resistance and the input capacitance values are also available.
