Abstract

fetched live from OpenAlex

For the analysis of the characteristics and behavior of circuits prior to fabrication and to improve circuit performance, simulations using Spice tools are typically performed. Such tools rely on static compact models describing the behavior of the individual circuit components such as transistors. In reality, the behavior of the transistors changes over time due to aging, for instance, as a consequence of bias temperature instabilities (BTI). BTI is typically referred to as a drift of the threshold voltage of a transistor due to charge trapping at oxide and interface defects. To explain BTI, power-law-like mathematical expressions are often employed. However, using these simple formulas, the experimental data can only be replicated with limited accuracy. To evaluate the performance of logic inverter circuits made from 4H-SiC CMOS transistors with high precision, we use a physics-based defect model to describe the change of the device behavior from a defect-centric perspective. Our results indicate the limitations of using power-law-like formulas as they lead to an overly pessimistic estimation for circuit parameters.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
