Abstract
A low-voltage 3.0-5.6 GHz VCO was designed and fabricated in an 0.13 /spl mu/m SOI CMOS process. This VCO features a single-loop horseshoe-shaped inductor and an array of band-switching accumulation MOS (AMOS) varactors. This results in good phase noise and a wide tuning range of 58.7% when tuned between 0 to 1.4 V. At a 1 V Supply (V/sub DD/) and 1 MHz offset, the phase noise is -120 dBc/Hz at 3.0 GHz, and -114.5 dBc/Hz at 5.6 GHz. The power dissipation is between 2 and 3 mW across the whole tuning range. The buffered output power is -7 dBm. When VDD is reduced to 0.83 V, the VCO dissipates less than 1 mW at 5.6 GHz.

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
