Parameters

Name Description Unit Type Default
ID Element ID Text IC1
W Ribbon width Length 0 um
T Ribbon thickness Length 0 um
H Substrate thickness Length 0 um
Rho Resistivity relative to gold   0

Implementation Details

This circuit component models a ground conductor having a rectangular cross section. The model is implemented as a lumped element series inductor and resistor whose values are derived from the dimensions and resistivity of the ribbon.

Layout

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.

Restrictions

Recommended 0.005 ≤ W/T ≤ 200 Required
0 ≤ Rho ≤ 100 Recommended L/λo ≤0.2 Recommended

Recommendations for Use

Discontinuity models function most accurately when attached to lines that match their corresponding edges. Directly connecting discontinuity models to one another reduces their accuracy.
