[Ngspice-users] Periodic Steady State analysis and Two tone test

[Balaji <bal...@gm...>]

Hello,

1. I have a circuit with very large input voltage range. I need to perform
an AC-like analysis to find its bandwidth. I have already done AC analysis,
but feel that large signal AC analysis is not suitable for high input range
devices. Periodic Steady State Analysis has been suggested. Can anyone help
me with this? Does Spice3f5 support PSS? If yes, how do I perform it?

2. I have performed a transient analysis and found harmonics to compute the
THD. But I am told that a two-tone test - IIP3 is better than THD analysis.
Can anyone please help with this?

Thanks,
