Mutual Inductors

The Spectre mutual_inductor device is translated as an ADS mutual inductor.

Example Spectre Command Line:

l1 (1 0) inductor
l2 (2 0) inductor
ml1 mutual_inductor coupling=1 ind1=l1 ind2=l2

Spectre Netlist Syntax:

name mutual_inductor [param= value ]*

ADS Netlist Syntax:

Mutual: kid K= value Inductor1=" lid1 " Inductor2=" lid2 "

ADS Schematic Symbol:

Instance Parameters:

Comments:

• The ADS Schematic symbol for an individual inductor uses a slash on the wire near pin 1 as opposed to the standard dot used in Spectre.

• ADS Schematic Symbol: Note that the MUTIND on the left is the symbol placed when the K is read. The example on the right is an illustration of the referenced inductors.

• ADS allows a coefficient of coupling between -1 and 1.
