i am simulating zero -IF receiver for wimax.
i want to calculate 1 dB compression point but in HB it is not allowing 0 Hz as output frequency.
and for 3 mixer tones what is the iip3 equation

The switched capacitor integrator is as following. how to test the linearity of the integrator? I am considering to do it in following way.
1) Input is a pure sin wave, the do pss+pac, then calculate the iip3
2) input is a pure sin wave, the output is a stair-case sin wave, then sample the output and do DFT the watch the HD3.

Write your iip3 equation in the outputs menu and then make your simulations by changing bias current utilizing parametric simulation.So, when you change bias current, for each step PSS+PAC will calculate iip3 and you'll obtain iip3 vs bias current curve.

i think u can replace the Iand Q with single path
just to calculate the total NF , gain , and iip3
then apply the result to I and Q

calculate it , or simulate , it
if u want to calculate it , check the book of the razavi , RF microelectronics , it is very good

I know the expression of
it leads to
to get P_in,max, let P_im,in=F (noise floor).
There are two variables in equation, P_in,max and P_iip3.
In RF system design, which one should be (...)

If you had obtain the Intermodulation Intercept Point, Noise Figure and Gain/Loss of the various analog block within your design then from which you can then calculate the overall system noise figure and iip3.
You could find the detail calculation example in Razzavi's RF IC Design.

Because it lacks for display function like NF, iip3 and 1dB point, another fatal problem is that it can't show data on smith map. You still can write your own equations to compute these parameters but its not intuitive.
For linearity analysis, most people use FFT to calculate the 3rd order or 2nd order IM term. But it needs a long time to do a
