Parameter Details

SCALING

Although all the Ln parameters except L0 technically do not have units of inductance, they are treated as if they do. For example, if L2 = 0.1 and project units are nH, it is evaluated as 0.1·10-9 H. This is done to simplify parameter extraction.

The flux Φ(V) is scaled in proportion to SC.

Implementation Details

The inductance is given by

And the corresponding flux by

If I < ITH,

Node 1 is the positive terminal.

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.
