Analyze and design 10-GHz 0.8-V<inf>DD</inf> -117dBc/Hz quadrature LC-VCO in 120nm CMOS technology
Bibliographic record
Abstract
A low supply voltage low phase noise 10-GHz CMOS quadrature LC-VCO (LC-QVCO) is systematically analyzed and designed for low power applications in wireline and wireless communication systems. Using a semi-empirical model, the impacts on VCO oscillation magnitude, loaded quality factor (Q <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">loaded</sub> ), and oscillation frequency from the parasitic components of passive and active devices are formulated in simple mathematic equations. The predicted VCO performance and the widely used linear model of LC-QVCO are verified by time-domain simulations, frequency-domain total loop gain analysis, and measurement data based on a 120 nm RF CMOS technology.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
