As VBIC includes the self-heating effects and the quasi-saturation modeling, VBIC model is the more advanced one compared to simple Gummel-Poon model. Knowledge*ON provides, for more accurate circuit simulation, its precise HBT VBIC model to our customers with and passive libraries resulting in reduction of foundry iteration time before manufacturing stage.
Using Knowledge*ON¡¯s accurate VBIC model, RF designers who are willing to make better outputs in better condition, will benefit and will be able to save cost that used to be consumed due to foundry model inaccuracy.
