Hello,

I need to simulate the harmonic distorsion of two OpAmps (ADA 4817 and AD 8033 and maybe other similar) at different frequency (range Dc to 20Mhz).
I am lucky to have access to Orcad Pspice. Unfortunately the models provided by Analog Devices tell " distortion is not characterized ".
Any suggestion or workaround ? Thank You.
The only way I have find is to build the prototype and measure the distorsion with generator and oscilloscope, but this is time consuming...
 

No, you do not any easy alternate. You need to have model for that. Can you share the circuit you want to simulate, may be seeing that people comment on possible sources to introduce harmonic distortion in simulation.
