Abstract
In this paper, a multiphase 18 GHz voltage-controlled oscillator (VCO) based on the rotary traveling-wave principle is presented. Using a 0.25 μm BiCMOS process, the fabricated bipolar VCO achieves a tuning range of 700 MHz and a phase noise of -98 dBc/Hz at 1 MHz offset from the carrier frequency. The oscillator shows high output power of -5.5 dBm and it provides 8 different phases. The VCO core consumes 13.5 mA of current. The performance of our proposed VCO is comparable with other published CMOS VCOs operating at the same frequency, but provides more phases and consumes lower current.

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
