I am trying to reproduce some of the figures found in the document, sc-netlists.pdf. Specifically the ones on pp. 14-15, figures 6-8. I have run through the simulations and it is clear that the setup for each simulation doesn't directly correspond to these figures. Even though I can come close, it would be very convenient to be able to reproduce them identically, within reason.

Thanks for the reply.

I have downloaded the netlists and have run the simulations many times. The results I have obtained do not appear to directly map to the figures to which I referred in the document. I am confident that it is simply a misunderstanding on my part.

For example, Figure 8 illustrates the transfer functions from the input, for sidebands up to +/- 25, to the output at baseband. The graph shows transfer functions out to ~10MHz, but in the pss analysis statement, maxacfreq=6MHz. It is not clear to me how the pxf analysis can evaluate sidebands beyond maxacfreq.

Now that I have the right circuit running, I can reproduce Figures 6 and 7 from the document, but my attempt at Figure 8 is not quite what you display in the document.

I am running the tah.ckt netlist using spectre version 6.1.0.151.

Thanks,

Ken,

Thanks again for the assistance, I have confirmed the simulation results match Figure 8.
