A 0.084 nJ/b FSK transmitter and 4.8 μW OOK receiver for ISM-band medical sensor networks
Bibliographic record
Abstract
This paper concerns a high performance transmitter (Tx) and an ultra low-power receiver (Rx) dedicated to medical implant communications operating at Industrial, Scientific and Medical (ISM) frequency band. Tx benefits from a new efficient Frequency-Shift Keying (FSK) modulation technique which provides more than 20 Mb/s of data-rate and consumes only 0.084 nJ/b validated through post-layout simulations using 1.2 V supply. The On-Off Keying (OOK) Rx consists of a noncoherent detection design based on envelope detector scheme. The proposed receiver was simulated with modulation index ranging from 60 to 100%. Data-rate of 2 Mb/s was achieved while consuming 4.8 μW from a 0.9 V supply. The proposed circuits are implemented in 90 nm CMOS technology.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
