Abstract
This paper presents a step-by-step methodology for simultaneous noise and input impedance matching in CMOS and SiGe W-band LNAs. This technique yields either increased gain or reduced power dissipation. Additionally, techniques to determine the optimum layout for MOSFETs in mm-wave LNAs are discussed. Measurement results in 90nm CMOS show a 1-stage 1.8V, 78GHz LNA with 3.8dB gain and 16mW power dissipation, and a 1.8V, 2-stage 94GHz LNA with 4.8dB gain, and 30mW power dissipation. In all cases S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> and S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">22</sub> are lower than -10 dB

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
