Abstract
This paper deals with the design methodology and characterization of a novel integrated differential phase shifter suitable for RF communication systems. The differential phase shifter is realized using a cascade of /sub 0//4 varactor tuned LC ladder networks connected between driving amplifiers and is designed in a conventional 0.18 /spl mu/m CMOS operating out of a 1 V supply. The circuit provides up to /spl pi//3 (rad) maximum phase shift for every segment of the LC ladder network (twice as reported in previous work). The implemented differential phase shifters; provide up to 2/spl pi/ (rad) absolute phase shift and /spl pi/ (rad) relative phase shift with sine phase transfer functions for 8 GHz RF signals. Each differential phase shifter occupies an area of 400 570 /spl mu/m/sup 2/ and dissipates 170 mW.

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
