Fully-integrated multi-band tunable linearized CMOS active analog phase shifter with active loss compensation for multiple antenna wireless transceiver applications
Bibliographic record
Abstract
The design of a fully-integrated multiband tunable linearized CMOS active analog phase shifter with active loss compensation that has broadband signal transmission and provides multiband phase shifting and that allows for broadband distortion reduction is presented. The S21differential power gain peaks at 7 dB and then rolls off to a unity gain bandwidth of 11.5 GHz. The simulated phase S21shift tuning performance is better than 50 degrees at multiple bands of 2.4 GHz and 5.8 GHz. The simulated linearized phase shifter IIP3 show a 10 dB improvement. Simulation results show that the co-design of the active analog phase shifter with on-chip loop antenna in both transmit and receive path has phase S21shift tuning performance which is better than 50 degrees and is compared to a stand alone on-chip loop antenna S21phase performance. The CMOS active analog phase shifter was fabricated using the 0.13 mum CMOS technology and has a total silicon chip area of 1.887times0.795 mm2.

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.
