Title: spectre pss & pac
Post by vlsi_design on Jan 13^th, 2015, 6:59pm

I have simulated mixer gain using pss+pac and considered 8 harmonics. In direct plot form when I choose sidebands I get a list of input sidebands and output sidebands.

What are input sidebands? Are they harmonics of LO due to input non-linearity? I understands the output sidebands.

As per cadence manuals, pac simulates gain from one input one input sweep range to several outputs & several output frequency ranges offset by LO. This is contradicted by list of input harmonics which indicates it is not one input range.
