Abstract
BiCMOS topologies for mm-wave voltage-controlled oscillators and frequency dividers are presented. The topologies, based on a MOS-HBT cascode configuration, enable low-voltage operation without compromising speed. A 37-GHz Colpitts VCO with 8% tuning bandwidth is reported with a phase noise of -97 dBc/Hz at a 1-MHz offset. For the first time, experimental evidence confirms that the bias condition for optimal VCO phase noise coincides with the bias point for minimum noise figure. Additionally, frequency division up to 70 GHz is reported, which is believed to be a record for dividers employing n-channel MOSFETs.

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
