A 14b threshold configurable dynamically latched comparator for SAR ADCs
Bibliographic record
Abstract
This paper presents a dynamically latched threshold configurable comparator to eliminate the DAC in conventional SAR ADC designs. The comparator uses intentional circuit asymmetry to generate precise threshold or offset voltages. Four offset stages with resolutions of 15.5 μV, 316 μV, 7.9 mV and 29.85 mV are superimposed to yield a 282.6 mV <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pp</sub> tuning range. The high resolution is obtained by exploiting submicron deviations in device dimensions. The comparator has been designed and tested in 0.13 μm digital CMOS. DC measurements yield 14 bit resolution with 0.38 INL and 0.41 DNL. AC measurements at 6.25 MHz correlate well with the DC measurements. Noise is bandlimited to allow for sampling up to 50 MHz.

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.
