Abstract
A 15-bit low-power incremental ADC is designed for sensor applications. The ADC is designed to be frequency-scalable by 1000 times from 1.67S/s to 1.67kS/s. To reduce power, an opamp with class AB characteristics is used. The design was fabricated in 0.18/μm CMOS and occupies an area of 0.35mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . Configured to operate at full-rate as a Delta-Sigma modulator, the ADC achieves 91.8dB peak SNDR while consuming 83μW from a 1.8-V supply. Operating as an incremental converter, the ADC powers off periodically to achieve frequency scalability, maintaining 84.7dB to 88.9dB peak SNDR while operating from 1.67S/S to 1.67kS/s and scaling analog power by up to 500 times.

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
