A Two-Phase, Single-Comparator, Comparison-Reference-Free Level Crossing ADC for Time-Sparse Applications
Bibliographic record
Abstract
A novel discrete-time, level-crossing analog-to-digital converter (LC-ADC) is proposed in this paper. The proposed LC-ADC exploits only one comparator for fully-differential implementation. By using a single comparator twice for each sample instead of using two separate comparators, significant area saving is achieved. The proposed DT LC-ADC is implemented using 180-nm standard CMOS technology with 8 bits of resolution, targeting a 10-kHz bandwidth. Post-layout simulation results indicate that the ADC consumes 18.94μW for a 10-kHz input signal at a supply voltage of 1.2 V. The LC-ADC achieves 11.16-bit ENOB, 68.96 dB SNDR, and 79.95 dB SFDR within the signal bandwidth, and 8.22-bit ENOB, 51.29 dB SNDR, and 55.73 dB SFDR over the full bandwidth.

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.
