tidy3d.SSACVoltageSource

class SSACVoltageSource

Bases: Tidy3dBaseModel

Small-Signal AC (SSAC) voltage source.

Parameters:

• name (Optional[str] = None) – Unique name for the SSAC voltage source.

• voltage (ArrayLike[dtype=float, ndim=1]) – [units = V]. List of DC operating point voltages (above ground) used with VoltageBC.

• amplitude (float = 1.0) – [units = V]. Amplitude of the small-signal perturbation for SSAC analysis.

Notes

This source represents a small-signal AC excitation defined by a DC operating point voltage and the amplitude of the small signal perturbation.

The voltage refers to the DC operating point above the simulation ground. The amplitude defines the magnitude of the small-signal perturbation. Currently, full circuit simulation through electrical ports is not supported.

Examples

>>> import tidy3d as td
>>> ssac_source = td.SSACVoltageSource(
...     name="VIN",
...     voltage=0.8,  # DC bias voltage
...     amplitude=1e-3  # Small signal amplitude
