A novel multichannel analog-to-time converter based on a multiplexed sigma delta converter
Bibliographic record
Abstract
In this paper, a new sigma delta modulator based on a multiplexed input topology is proposed to decrease power consumption and size in implantable bio-interfacing systems. An opamp sharing technique is employed in order to process several input sequentially. The proposed sigma delta modulator integrates each input separately and stores the integrated value inside a dedicated capacitor. We show that the resulting transfer function of the modulator is equivalent for all channels. The proposed circuit has been implemented in a 180-nm TSMC process. The circuit includes 4 channels and consumes 11.5 μW per channel, provides an ENOB of 7.8 bits, and presents a bandwidth of 10 kHz. The chip area for the proposed design is 150 μm × 135 μm for 4 multiplexed inputs.

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.
