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:

For information on parameter format, refer to Using Parameter Mapping Tables to Understand a Translation

Table 7-6. Mutual Inductors Parameter Mapping

ADS Name	Unit	Default	Spectre Name	Unit	Default
K			coupling		0.0
Inductor1			ind1
Inductor2			ind2
Parameters not in Spectre Model
M	H

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.
