GroundLifted

class pmrf.models.composite.nodal.GroundLifted(lifted: Model, *, name: str | None = None, metadata: Any = None)

Bases: Model

A wrapper that converts an N-port grounded model into a 2N-port ungrounded model.

The inner component’s signal paths map to the even ports (0, 2, 4, …, 2N-2). The inner component’s ground is lifted and connected to the odd ports (1, 3, 5, …, 2N-1), forming an isolated common-return star node.

Parameters:

• lifted (Model) – The inner N-port model to be wrapped and lifted from the global ground.

• Reference

• ----------------------

• S-matrix (Constructs a \(2N times 2N\) floating S-matrix by superimposing the signal)

• ports. (onto the even ports and a parallel star-node (common return) S-matrix onto the odd)

lifted: Model

The inner N-port model to be wrapped.
