Abstract
A low power 32nd-order digital filter for portable audio applications has been designed and implemented in a single threshold 1-V 0.5-/spl mu/m CMOS process. The design is full custom, using a combination of conventional CMOS and pass-transistor circuits, optimized for low energy consumption and small area. The filter features up to 16 biquad sections with programmable coefficients and performs fixed-point computations with 16-bit resolution. The measured average energy consumption of 330 pJ per biquad computation indicates that the implementation of complex digital signal processing in a single-threshold low-voltage process is a viable alternative to implementations in multiple threshold processes.

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
