Abstract
A pipelined ADC architecture for use in sub-sampled systems which has its power scaleable with down sampled bandwidth is presented. Using a technique developed to eliminate the front end sample and hold, a power savings of >20% is achieved compared to a previous design. A technique to improve the settling behavior of Rapid Power on Opamps is also presented. Measured results in 1.8V 0.18μm CMOS verify the removal of the front end sample and hold does not cause gross MSB errors for input frequencies higher than 267MHz.

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
