Kxxxxxxx

Coupled (Mutual) Inductors: This device is translated as a mutual inductor.

Example SPICE Command Line:

k1 L1 L2 .5
L1 1 3 10
L2 2 4 20

SPICE dialect and netlist syntax:

Spice2/3:

k id lid1 lid2 value

PSpice:

k id lid1 lid2 * value

HSpice:

k id lid1 lid2 [ K= ] value

ADS Netlist Syntax:

Mutual:k id K= value Inductor1=" lid1 " Inductor2=" lid2 "

ADS Schematic Symbol:

Instance Parameters:

kid = Mutual inductors element name
lid1 = Name of the first coupled inductor.
lid2 = Name of the second coupled inductor.
value = The coefficient of coupling, K, which must be greater than 0 and less than or equal to 1.

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 SPICE. 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.

For value, HSpice and ADS allows a coefficient of coupling between -1 and 1.

PSpice supports a mutual inductor syntax that allows any number of inductors to be coupled together with the same coupling coefficient. This needs to be converted to a set of mutual inductors representing every possible combination of inductors from the list. The translator does not support this at this time.
