spectre iip3
I have a problem with my IIP3 simulation. In my receiver system, I have an LNA and a Mixer connected together and I want to simulate the IIP of the whole chain by using Spectre. I follow the manual from Cadence by using PSS+PAC analysis to simulate it.
The result shows that the slope of the third-order curve is not exactly 3. It varies around 3. Are there any ideas about simulating IIP3 to get the slope for the third-order curve equal to 3?
Thanks in advance
