Does any other have good to extract the MOM-cap (cap fringer) , Now I design
0.18um MOM-cap with VIA. I use calibre to do extraction, But I found the command files mo define VIA-to-VIA information, So that the cap is low than the practical ,DOes anyone have good method to expect the value. Thanks
I attach a short application note "MOM capacitor design challenges and solutions" that addresses the questions discussed here.
Regarding vias - if you remove vias, this would decrease capacitance density and probably increase series resistance of MOM capacitor. Don't do this if you want to achieve maximum possible capacitance density.
