Differential rail‐to‐rail voltage‐controlled quadrature ring oscillator for low‐power implantable transceivers
Bibliographic record
Abstract
A new low‐power rail‐to‐rail voltage‐controlled quadrature oscillator is presented. This oscillator was implemented to provide the frequency deviation of frequency‐shift‐keying (FSK) modulation in implantable radio‐frequency (RF) transceivers. The quadrature oscillator circuit generates differential in‐phase and quadrature‐phase ( I and Q ) signals in a two‐stage ring configuration. The proposed structure of delay cells and the start‐up circuit were implemented using IBM 130 nm CMOS technology. The frequency can be tuned between 300 kHz and 11.57 MHz by varying the supply voltage from 0.35 to 0.9 V. An average current of 5.5 µA (2.5 µW) was consumed to generate rail‐to‐rail differential quadrature signals with a frequency of 2 MHz as the target operating point dedicated to low‐power implantable transceivers.

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.
