Abstract
Abstract A Doherty power amplifier (DPA) with a self‐adaptive biasing circuit is presented in this letter. The proposed structure is integrated into the gate biasing network of the peaking power amplifier (PA), and then the gate voltage can be adaptively adjusted with the input power. Due to the presence of this simple but effective circuit, the peaking PA can approach the ideal power transfer characteristic which results in better efficiency than the conventional design with constant biasing. The proposed circuit is implemented and compared with both the conventional DPA and a single Class‐AB PA. 12% and 34% power added efficiency improvements are achieved at 6 dB backoff, respectively. © 2011 Wiley Periodicals, Inc.

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
