A high-sensitivity battery-less wake-up receiver for 915 MHz ISM band applications
Bibliographic record
Abstract
A high-sensitivity fully passive 902-928MHz ISM band wake-up radio (WuRx) receiver for implantable biomedical devices is presented. The WuRx does not have an external power source and harvests the entire energy from the radio-frequency (RF) signal received at the antenna. A high-efficiency differential RF-to-DC converter rectifies the input RF signal and supplies the circuit blocks including a low-power comparator and reference generators; and at the same time retrieves the envelope of the On-Off Keying (OOK) wake-up signal. To enhance the power conversion efficiency (PCE) of the proposed rectifier when the input power is low, appropriate gate-drive voltages for each stage of the rectifier are generated using a chain of auxiliary cells. The WuRx is designed and implemented in 0.13 μm CMOS and achieves a sensitivity of -43 dBm for a 100 kbps wake-up signal.

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.
