Abstract
This paper presents the design of an efficient two-stage m illim eter-wave power amplifier (PA) using stacked field-effect transistors in 45nm silicon-on-insulator (SOI) CMOS technology. It highlights two major issues encountered when designing single-ended multistage PAs at millimeter frequencies (e.g., 60GHz), namely the significant source to ground parasitic inductance and the vulnerability to oscillation at low frequencies. The two-stage differential PA includes input, inter-stage and output matching networks implemented using RF transformers with a high coupling factor and reduced insertion losses. The PA demonstrator showed a 3-dB bandwidth equal to 12GHz (55-67GHz). The small signal gain, peak power added efficiency and peak output power were recorded as 14.5dB, 25% and 17.3dBm, respectively.

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
