Title: inductor model
Post by tideblue on Apr 16^th, 2009, 5:00am

Hi,
I found in my model file that the variation of inductor at different models could be up to +-15%. And the parasitic resistance and capacitance are correlated(when Rs is max,Cox is min and vice versa)
I can not find any theoretical explanation on the big variation of L and the correlation.
Do you think these numbers are trustworthy?

About the correlation, I suppose Rs is min, the metal width is max, thus the parasitic cap is max, if you still want the same inductance.

what do you mean by different models? Do you have different models for one inductor in your lib?
