A +18 dBm broadband CMOS power amplifier RFIC with distortion cancellation
Bibliographic record
Abstract
A broadband fully-integrated class-A power amplifier (PA) is presented using derivative superposition (DS), which delivers +18 dBm of saturated output power from 1 GHz to 6 GHz. The PA exhibits a flat power gain of 13.5 +/- 1.2 dB over its operating frequency range. It features a high linearity with an output 1dB compression point (OP1dB) and third order intercept point (OIP3) of more than +16 dBm and +25 dBm respectively. The measured OIP3 remains above +25 dBm, i.e. 9 dB higher than OP1dB, for a wide range of power levels up to 4 dB backoff from OP1dB. The chip was fabricated using a 0.13 μm CMOS process, occupying an active area of only 200 μm x 110 μm.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
