Abstract
Frequency synthesis in modern wireless transceivers requires high frequency, and for many circuit architectures, increased tuning range. In this work, a novel large-tuning range injection locked RF division integrated circuit is presented. The fabricated design operates from 6.2 GHz to 11 GHz. A benchmark Colpitts divider was fabricated on the same silicon. At a 10 kHz offset from the carrier, the inductorless divider has a measured phase noise of -112 dBc/Hz and consumes 17.5 mW from a 3.3 V supply, whereas the Colpitts divider has a measured phase noise of -107 dBc/Hz and consumes 11.7 mW from a 3 V supply. The new architecture also reduces the dependence on quality factor of integrated components for LC-resonant structures by utilizing transistor and layout parasitics at the frequencies of interest. The new inductorless injection locked divider has a very flat output power characteristic over the division range.

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
