Time-invariant behavioral modeling for harmonic balance simulation based on waveform shape maps
Bibliographic record
Abstract
A new time-domain time-invariant periodic nonlinear behavioral model for multi-port systems is formulated from first principles in this paper. Unlike frequency-domain behavioral models like the Poly-Harmonic Distortion (PHD) model that describe the output frequency spectral components of the system, this black-box approach provides a time-invariant map of the discrete-time representation of the input waveform shape to the discrete-time representation of the output waveform shape, resulting in a reduction of the number of describing functions compared to a frequency domain description of the system. A two-port transistor behavioural model implementation for harmonic balance simulation is presented. The validation results show that the proposed model is capable of modeling the steady-state periodic output of multi-port nonlinear time-invariant systems and has potential to assist in the computer-aided design of RF systems with nonlinear components.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
