how to simulate a full-differential op amp?

[xdy83]

such as cmrr psrr slew-rate settling-time and so on.
can anyone provide the simulating schematic? or some reference?
thanks

You can create the simulation way as long as you understand the principle.such as SR, you can fix common mode and change diff mode voltage.

For fully diff op amp, use ideal balun in your diff mod signal sim.
In terms of cmrr, psrr, you have to use post-layout sim (R-C extracted view) in your sim. Plus Monte Carlo.
Schematic sim would just give you some number totally nonsense.
