Abstract
A third-order passive switched-capacitor low-pass filter is presented together with experimental results. The current input-voltage output filter structure realizes complex-conjugate poles although it is composed of switches and capacitors. The results are verified with measurements performed on the filter prototype integrated in a 0.13-μm CMOS technology. The prototype has a cut-off frequency of 470 kHz, 150-μW power consumption from 1.2-V power supply, 92-dB SFDR, and an active area of 0.06 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The switch-capacitor filter was obtained using a continuous-time model that is also described here and is useful for design, analysis, and simulation of oversampled switched-capacitor circuits. The model is applicable to a variety of topologies including multi-phase passive switched-capacitor filters, switched-capacitor integrators, as well as switched-capacitor dc/dc converters.

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
