Polar Diagram in Cadence ?

[Guenther Sohler]

If I have an amplifier with an AC Response,

is it possible to display this as a polar diagram in Analog Artist ?
(instaead of displaying magnification and phase separately )

I could not see such a function in the calculator

Hi,

You need a complex data to plot with a polar view.
I just made a little RC filter, run a simple pz analysis (Pole Zero).
I then hit ADE->Results->Direct Plot -> Main Form
and the choose :
PZ analysis, poles and zeros function and then Plot.
By default, my wavescan pops up with a rectangular view. I then wen to
WaveScan -> Graph -> Display Type -> Polar. This comes with the polar
view as you can see here-enclosed.

The Calculator/Wavescan documentation will give you more details.

Hope it help !
