Abstract
A novel mixed-mode adaptive equalization system for a high-speed 2-level pulse-amplitude nodulated (PAM) signal is presented. The intended application is in the area of digital serial interface, such as a non-return-to-zero-inverted (NRZI) serial video signal with a data rate of 270 Mbits/s. The adaptive system tunes the zeros of a finite-impulse-response (FIR) analog programmable filter. Programmable differentiators and transconductors are designed to increase the tuning range of the filter. An average error, obtained by calculating the accumulated area of the eye-diagram, and average gradients are proposed as inputs to a digital least-mean-squared (LMS) algorithm. This approach allows a more relaxed speed requirement for analog-to-digital converters (ADCs). A third-order analog filter, along with some essential circuit blocks, are designed for a 0.35 /spl mu/m CMOS process.

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
