Abstract
This paper describes the design of an analog receiver front-end targeting multi-gigabit data communications over large-core plastic optical fibers. A receiver front-end with an integrated photo detector has been implemented in a standard TSMC 65 nm low-power bulk-silicon CMOS process. A novel hybrid current buffer based transimpedance amplifier has been proposed to drive the 14 pF photo capacitance presented by the large-area photo detector to multi-gigahertz range. A digitally controlled slow-slope equalizer has also been integrated in the receiver front-end to compensate the high-frequency losses due to the integrated photo detector. The receiver front-end consumes 50 mW dc power from a 1.2 V supply (excluding output buffer) and achieves an NRZ data rate up to 3.125 Gbps.

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
