Title: Modeling of coupled inductors?
Post by weber8722 on Mar 13^th, 2015, 1:37am

Hi,

how can we model e.g. in verilogA coupled inductors efficiently?
I also wonder about a special topic: It is wellknown and simple to transform a pair of coupled inductors (i.e. a transformer) into a T-circuit. But is this also possible with 3 or more coupled inductors (all grounded at one side)?
Found nothing in the internet unfortunately.

Are the inductors themselves in Verilog-A, or do you just want to model the coupling in Verilog-A? I'm not aware of a way to pass the instance names of external inductors into a Verilog-A module to do the coupling.

If you're doing everything in Verilog-A, the only thing I'd caution you about is to make sure the scaling is done properly. Think about what the unknowns are and how the simulator tolerances will apply.
