Abstract
This paper describes an analog multi-tone receiver capable of processing three data streams running at 15 Gb/s, one in baseband and two in quadrature over carriers at 15GHz, achieving an aggregate rate of 45Gb/s over a single physical channel. The receiver maximizes bandwidth efficiency by using orthogonal sub-channels and avoids the need for analog to digital converters by incorporating a mixedsignal MIMO equalizer that can mitigate inter-symbol interference and inter-carrier interference. The system is designed and laid out in a 22nm FDSOI technology. Post-layout simulations are employed to verify the effectiveness of the proposed architecture, demonstrating a raw BER of 10−5 over a channel with an insertion loss of 14dB at 28GHz is achieved. The complete system has an energy efficiency of 6.6pJ/bit and occupies an active area of 0.29 mm2.

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
