Reply #1 - Aug 22^nd, 2014, 1:33am Hi, you can run an s-parameter analysis and sweep frequency. You can then calculate Q using the Y or Z parameters that are generated. regards, Aaron

You measure the impedance of the inductor by driving it with a current source in AC analysis, then you can extract the Q from the results. -Ken
