Hi all,

the attached is the oip3 simulation result of a Gm-C filter, it's confusing that the IM3 is away from 3× slope line, and not smooth at all, could anyone explain it to me the reason?

Thanks in advance

You can expect regular IM3 curves with wideband circuits, e.g. amplifiers. There are many possible reasons why the large signal behaviour of a filter might look different. Watching the related waveforms may explain the observations.
