Hi.

I am simulating I/Q mixer using QPSS. QPSS is going through many stabilisation iterations (about 60) with conversion norm changing very little between these iterations. Once Newton iterations start, QPSS converges with 2 iterations.

But, due to the large number of stabilisation iterations, QPSS takes a very long time to complete. Can anyone point out why QPSS could be going through so many stabilisation iterations?

Hi Murat,

Thanks for your reply.

I have tried using flexible balance. But I don't get reliable results. This may be because my mixer is too non-linear for flexible balance to give good results.

Today I tried setting the stabcycles parameter. With this I was able to limit the number of stabilisation cycles and reduce the total simulation time for QPSS.

with regards,
Sandeep
