High-speed signal compensation on printed circuit boards
Bibliographic record
Abstract
Data transfer rates on printed circuit boards have approached speeds that challenge the limits of today's technology. Chip-to-chip digital communication has reached a plateau at 3 Gbit/s and several problems need to be addressed to significantly increase data transfer rates. Crosstalk between adjacent signal lines increases with increasing frequency. With far end crosstalk (FEXT), inductive and capacitive components conveniently cancel each other as they propagate on an interconnect transmission line. However, with near end crosstalk (NEXT), these components add together and interfere with signals on adjacent receivers. This paper proposes a solution for canceling crosstalk by adding extra circuitry to the receiver within the integrated circuit. The digital circuit delivers one of three appropriate levels of crosstalk compensation to the incoming signal. Since the compensation circuit is of low complexity, it can be efficiently integrated into existing CMOS designs.

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.
