Hello experts,
I have a question on the PGS performance. I am now simulating a silicon-based transformer in HFSS and want to see the performance of the Patterned Ground Shield (PGS). From the simulation results it seems that the polysilicon PGS can give a higher Q-Factor than the metal PGS with the same size, shape and clearance to the coils. I was wondering if you can help me to analyze why the polysilicon is better in the sense of Q improvement even though poly's conductivity is low?
Thank you in advance!
