Design of A 128 × 128 CMOS APS with extended noise suppression for high and low light imaging applications
Bibliographic record
Abstract
A third generation of CMOS Active Pixel Sensor (APS) for high and low light imaging (HaLLI) applications is presented. The sensor pixel 128 × 128 array features more feasible and robust circuit design than its predecessors, which allows for remarkable thermal (KTC) noise suppression, bringing the anticipated noise floor below 1e- rms. A new on-focal, column parallel, two phase, Single Slope (SS) 10 bit Analog to Digital Converter (ADC) was embedded as a step towards implementing an integrated Lab on a Chip (LoC) platform. Herein, we describe the main milestones of the chip components design along with simulated performance results obtained using 0.18um tool kit. The simulation results indicate that the proposed system achieves sub electron KTC noise, 10 bit of Effective Number of Bits (ENOB), 50dB Signal to Noise Ratio (SNR), up to 102dB Dynamic Range (DR) @ 33 frames per second. A 128 × 128 CMOS image sensor was fabricated in 0.18um process and successfully simulated.

How this classification was reachedexpand
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.
