Abstract
A new technique and circuit topology is proposed to readout the output of a capacitive sensor for lab on chip (LOC) applications. Using time-mode signal processing and adopting modified digital blocks, a first-order delta-sigma interface is developed. It offers an incredibly compact and low-power solution where analog precision is achieved by making advantage of digital design. The design is capable of being tuned for different ranges of input capacitance as well as different resolutions where applicable. The proposed circuit is layout in 0.8-mum DALSA CMOS process. Post-layout simulation shows a capacitance change of 5 fF can be measured with error less than 2% in 500 mus. Also, the resolution of the circuit can be increased by 25 times to measure an input capacitance as small as 0.2 fF.

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
