A 1.8-V 3-MS/s 13-bit ΔΣ A/D converter with pseudo data-weighted-averaging in 0.18-μm digital CMOS
Bibliographic record
Abstract
A 1.8 V /spl Delta//spl Sigma/ modulator, fabricated in a 0.18 /spl mu/m standard digital CMOS process, achieves 81 dB SFDR and 74 dB SNR over a 3 MS/s conversion bandwidth. Its single-loop single-feedback architecture uses a 3rd-order FIR noise-transfer- function and a 5 bit quantizer to render the quantization noise negligible at 16/spl times/ oversampling. A pseudo data-weighted-averaging technique linearizes the multibit feedback D/A converter, while eliminating the inband signal-dependent tones. The bootstrapped switches in the switched-capacitor implementation reduce the sampling distortion for a 1.85 V/sub pp/ input-signal range. The analog and digital power consumptions are 32.4 mW and 12.6 mW, respectively. The on-chip references dissipate 14.4 mW.

How this classification was reachedexpand
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.
