Ultra Low Power Transceiver for Wireless Patient Vital Sign Monitoring
Bibliographic record
Abstract
An ultra low power analog transceiver front end module for an FSK based fully differential 2.4 GHz transceiver in 0.18 mum CMOS technology is described in this paper. The transceiver consists of a programmable class C power amplifier, passive ring mixer and a matching circuit which provides the required load for the PA as well as matches the mixer input impedance to the antenna similar to that described in [1]. A new baseband module produces a pulse train corresponding to the transmitted information. Both the PA and the passive mixer are driven by a 2.4 GHz VCO similar to that described in [2], modified for low voltage operation. The simulated overall power consumption of the receiver chain is 150 uW and the overall PA efficiency is 36% for 240 muW transmitted power. The simulated phase noise of the 2.4 GHz VCO is -90dBc/Hz at 1 MHz offset and the power consumption of the VCO is 103 muW. The output frequency of the VCO can be varied by means of a control voltage to generate FSK modulation.

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.
