Abstract

fetched live from OpenAlex

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 S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</sub> differential power gain peaks at 7 dB and then rolls off to a unity gain bandwidth of 11.5 GHz. The simulated phase S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</sub> shift 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 S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</sub> shift tuning performance which is better than 50 degrees and is compared to a stand alone on-chip loop antenna S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</sub> phase 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 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .

Full frame distilled prediction

Teacher imitation

Not 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.
