Abstract
Avalanche photodiodes (APDs) operating in Geiger mode can detect weak optical signals at high speed. The implementation of APD systems in a CMOS technology makes it possible to integrate the photodetector and its peripheral circuits on the same chip. In this paper, we have fabricated APDs of different sizes and their driving circuits in a commercial 0.18-mum CMOS technology. The APDs are theoretically analyzed, measured, and the results are interpreted. Excellent breakdown performance is measured for the 10 and 20 m APDs at 10.2 V. The APD system is compared to the previous implementations in standard CMOS. Our APD has a 5.5% peak probability of detection of a photon at an excess bias of 2 V, and a 30 ns dead time, which is better than the previously reported results.

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
