Abstract
Small area and power efficient analog-to-digital converters are needed to accommodate implantable multichannel sensors. This paper concerns the design and implementation of an ultra-low-power 8-bit successive approximation analog-to-digital converter (ADC). A new topology is proposed which improves the conventional architectures by replacing the successive approximation register and the digital-to-analog converter by a switchedopamp switched-capacitor circuit which dissipates very low power. The sampling frequency of the proposed ADC is 30 kSps and within an input range of 600 mV. Implemented in a 0.18-μm CMOS process with a 1.8 V voltage supply, the ADC achieves a power dissipation of 7.4 μW and occupies an area of 0.04 mm2.

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
