Abstract
CMOS radio frequency class-E power amplifiers (PA) for GMSK/GFSK modulations have been designed and fabricated using 0.25/0.35/spl mu/m technologies. The operating frequencies are centred at 1.2GHz and 2.65GHz with 24-26dBm output power. Mode locking techniques are employed for both designs, in order to reduce the driving requirement. High efficiency broadband off-chip hybrid ring baluns are used at both input and output for converting signals from single-ended to differential and vice versa. Regular bonding wires are used as inductors for the 1.2GHz PA, and on-chip bondwires are used for the 2.65GHz PA. With a 1.3V supply, the measured power added efficiency (PAE) of the 1.2GHz PA, after taking into account the losses in the baluns, is 62%. The PAE for the 2.65GHz PA is 38% when operated from a 1.7V power supply.
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.
