Implementation Details

VDIODE1 is a nonlinear incremental model of the Schottky diode. It is equivalent to SDIODE, but is intended primarily for Volterra analysis. The DC junction bias voltage, VDD, is specified by the user, and the program calculates the Taylor series coefficients for both the resistive and capacitive parts of the junction. See the SDIODE element for equations.


This element does not have an assigned layout cell. You can assign artwork cells to any element. See “Assigning Artwork Cells to Layout of Schematic Elements” for details.
