Abstract
In this paper, an empirical nonlinear model for high electron mobility transistors (HEMTs) is presented. Unlike the conventional large-signal models whose fitting parameters are coupled to the measured I-V and C-V characteristics, the proposed modeling equations are direct formulated from the second-order derivative of drain current (I-V) and gate charge (Q-V) with respect to gate voltage. As a consequence, the proposed large-signal model is kept continuously differentiable and accurate enough to the higher-order I-V and Q-V derivatives. Measured and modeled results are compared for the 0.25µm gate-length GaAs pseudomorphic HEMTs (pHEMTs), and good agreement is obtained.

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 it
