Abstract
In this letter, a novel linear-in-magnitude RF envelope detector is presented which features high detection speed, low detection error and covers a wide range of carrier frequencies. The proposed detector topology employs a voltage-mode input stage which is AC-coupled to a full-wave rectifier. A prototype was implemented in a 0.13 μm CMOS process. Experimental results demonstrated a 3 dB operating frequency of up to 4.2 GHz and a maximal detection speed equal to 190 MHz. The input dynamic range ( ± 1 dB linear error) was 35.5 dB at 1 GHz and 25.3 dB at 3.5 GHz, 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
