Inductor with Optional Coupling (Closed Form): INDK

Symbol

Summary

INDK implements an ideal inductor with an option to include coupling to other INDK elements. The coupling is modeled by other elements (INDM or K) connected between the "K" ports of two INDK elements.

Parameters

Name Description Unit Type Default
ID Name Text L1
L Inductance Inductance 1 nH

Implementation Details

The INDK element implements an ideal inductor with the option to be mutually coupled to other INDK elements. The coupling between two INDK elements can be represented by using one of two elements: the INDM element, which represents the mutual inductance between the two INDK elements, or the K element, which represents the coupling coefficient. If nothing is connected to the "K" port of the INDK element, the inductor is considered ideal.

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.

Recommendations for Use

Figure 1 and Figure 2 show how these elements are typically used. Figure 3 shows how to model mutual coupling between more than two inductors.

Figure 1. Typical use of the INDK and INDM elements to model mutual coupling between two inductors. The INDM element is used to model the mutual coupling between the two INDK elements by specifying an actual mutual inductance.

Figure 2. Typical use of the INDK and K elements to model mutual coupling between two inductors. The K element is used to model the mutual coupling between the two INDK elements by specifying the coupling coefficient, K, and the inductances of the two coupled inductors.

Figure 3. Typical use of the INDK and INDM elements to model mutual coupling between more than two inductors. K elements could also be used in place of the INDM elements.
