I'm simulating a m9 spiral inductor with m1 ground ring in HFSS.
The L is close with data of PDK, but Q factor is very low compared with PDk.
I think the narrow is reason why Q factor is low, but as you see, ground ring indeed is narrow.
I think ground ring as current return path should not be high impedance.
Anyone can help me?
BTW, how to export PGS(pattern ground shield) from cell in virtuoso?
Thanks
