Hi

I have simulated cpw type inductor in HFSS. The inductance value at lower frequency such .1GHz to .4GHz is around 80nH to 40nH but the value from 0.5GHz is around 6nH upto resonance.



As per calculation i have designed the rectangular inductor for 7nH. But the results at lower frequency is very high. I feel which not proper.

I have simulated the same structure in coventorware MemHenry analysis., but we cannot get Q value in that tool.


Can you please tell what is mistake i have done in simulation.

Another thing, what are different methods adopted by HFSS and coventorware to calculate inductance.

what is error in between the value obtained by these tools.
