Analog triangular-to-sine converter using lateral-pnp transistors in analogue pCMOS process
Bibliographic record
Abstract
This paper focuses on the development of a monolithic analog triangular-to-sine converter that is based on the same technique as that devised by Barrie Gilbert [1977], which exploits the fact that a hyperbolic-tangent series converges to the sine. The novelty in the described circuit is the implementation of the sine shaper in CMOS process using lateral-pnp bipolar transistors. Due to the excellent performance of the used lateral-pnp transistors at low current levels, the elected circuit implementation is mostly appropriate for low-power operation. Experimental results from prototypes of the circuit fabricated in 0.6 /spl mu/m CMOS have shown that the deviation from ideal sine over the -/spl pi//2 to /spl pi//2 range is less than 0.5%.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
