Dear guys,
I want to estimate the effect of bondpad to my circuit's performance. I think the dominant effect is shunt parasitic capacitance. I used HFSS to simulate antenna, so I tried to simulate parasitic capacitance of bondpad but I don't know is my setting correct or not? When I extended the boundary, the result was changed! Thus how can I know the dimension of boundary area should be? Some guys said that it should be lamda/4, but in IC that length is too huge!!
Other guys also suggest the Sonnet software to simulate capacitance. I don't know how to use it. So if you have any tutorial, please share with me.
Thank in advanced.
