| Jul 13 at 18:13 | comment | added | 比尔盖子 | @kile Parasitics are approximated just as regular inductors and capacitors, use as many as necessary for the desired accuracy. But usually, the circuit is going to be tuned by trial and error anyway, so practical circuit designers don't really care about accurate parasitics modeling, which is difficult with many unknowns. Instead, roughly knowing they're "there" is sufficient (unless you're creating a reusable SPICE model for general use). In contrast, chip designers use parasitic extractions and field solvers extensively to model parasitics as best as they can, since tuning is not an option. | |
