Abstract

fetched live from OpenAlex

This paper describes a low-power, low-latency, 7–10  Gb/s burst-mode DC-coupled receiver for photonic switch networks. The receiver includes a transimpedance amplifier (TIA) followed by a three-stage differential amplifier. For burst-mode operation, DC and timing recovery loops work concurrently in the proposed architecture to achieve 5.8 ns lock time. The DC recovery loop employs a successive approximation algorithm to recover signal-dependent offset that takes only six cycles of C8 (1/8th of data rate) clock. The timing recovery uses a quarter-rate injection scheme that is immune to duty cycle distortion. The recovered clock jitter is 10 ps p-p for 10  Gb/s operation. The receiver consumes only 33 mW while operating at 10  Gb/s, and less than 2 mW (leakage power and bias circuit) during idle time. The completely inductor-less receiver occupies a 465  μm×265  μm area in 0.13 μm technology.

Teacher imitation

Not 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.
