Low-voltage, low-power and low phase noise 2.4 GHz VCO for medical wireless telemetry
Bibliographic record
Abstract
The design and simulation results of low-voltage, and low-power LC VCO is presented. The oscillator is used for portable wireless telemetry devices that operate under unusual supply voltage and power requirements. The VCO is designed to operate in the 2.4 GHz industrial scientific and medical (ISM) band. The novelty of this design is the low supply voltage which is equal to 0.4 V, about 100 mV below the threshold voltage of the MOSFETs used, and hence, the MOSFETs used are biased to operate in the sub-threshold region. The effect of the common-source inductor is also emphasized from the power consumption point of view. The VCO was simulated using CMOS 0.18 /spl mu/m process. The simulated performance characteristics are: power consumption of 41 /spl mu/W; phase noise of -123 dBc/Hz, -129.5 dBc/Hz and -133.1 dBc/Hz at offsets of 1 MHz, 2 MHz and 3 MHz, respectively; frequency tuning range of 18%.

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.
