Abstract
Summary A 902‐ to 928‐MHz industrial, scientific, and medical band transceiver using a wake‐up link for wireless body area networks wearable and implantable medical devices is presented. The design reaches exceptionally low‐power dissipation and provides an adapted data‐rate by gathering the advantages of frequency‐shift‐keying (FSK) and amplitude‐shift‐keying (ASK) modulation techniques. Transmitter (Tx) includes a new efficient FSK modulation scheme to generate up to 20 Mb/s of data‐rate and consumes around 0.084 nJ/b. The integrated receiver (Rx) is based on a new FSK‐to‐ASK conversion technique using on‐off keying fully passive wake‐up circuit (WuRx) with energy harvesting from radio frequency link. The adopted scheme leads to the scalability of energy consumption versus data‐rate at constant transceiver sensitivity, insuring high‐performances requirements. The transceiver is implemented in IBM 0.13‐ μ m CMOS process. The WuRx achieves a sensitivity of −53 dBm while the main receiver shows −78‐dBm sensitivity. Thanks to the simplified hardware, the receiver consumes only 640 μ W while the transmitter uses 1.4 mW from 1.2‐V supply voltage.

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
