A low‐power technique to boost the output amplitude of multi gigahertz push‐push LC VCOS
Bibliographic record
Abstract
Abstract A design technique to increase the output amplitude and hence the output power of push‐push LC‐based voltage‐controlled oscillators (LC VCOs) is presented that relies on LC resonance boosting of the second harmonic. Measurement results are in good agreement with the results predicted from the analysis. Using the proposed technique, a low‐power push‐push LC VCO is designed and implemented in 90‐nm CMOS. Based on the measurement results, the VCO has a frequency tuning range of 23%, from 20.1 to 24.8 GHz. It exhibits up to 8 dB improvement in its output power at the middle of the frequency band compared to a traditional push‐push VCO. © 2013 Wiley Periodicals, Inc.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
