WebCGS is the capacitance due to the overlap of the source and the channel regions by the polysilicon gate and is independent of applied voltage. CGD consists of two parts, the first is the capacitance associated with the overlap of the polysilicon gate and the silicon underneath in the JFET region. The second part is WebThe following table lists parameters for the three model levels according to DC and cv extraction in IC-CAP. (Some of these parameters are redundant and therefore only a subset of them is extracted in IC-CAP.) Table 76 describes model parameters by related categories and provide default values.
