Abstract
This letter describes a 4-GS/s four-way time-interleaved binary search analog-to-digital converter (ADC) in 65-nm CMOS. The ADC improves the conversion speed and resolution by concurrent binary searching on overlapping search space. After concurrent searching, the two successive approximation register ADC with reference offset generate 8-bit codes which are digitally interpolated to generate 9-bit code including 1-bit redundancy. Taking advantage of the higher conversion rate in the first two cycles and digital interpolation, ADC requires only six cycles to generate a 9-bit resolution at 1-GS/s rate. Consuming 28 mW, the implemented prototype achieves 39.56-dB SNDR and 48.21-dB SFDR at Nyquist frequency.

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
