A 0.13µm CMOS integrated wireless power receiver for biomedical applications
Bibliographic record
Abstract
This paper presents a fully integrated 2.2×2.2mm2, wireless power transfer (WPT) receiver in 0.13μm CMOS without any external components or post-processing steps. The on-chip receiver coil (Rx) demonstrates a peak measured WPT efficiency of -18.47dB, -20.96dB and -20.13dB at 10mm of separation through air, bovine muscle and 0.2molar NaCl, respectively. Fully integrating the large receiver coil along with supporting circuits introduces new challenges that are addressed in this paper. The receiver employs a synchronous adaptive matching network that guarantees the maximum achievable efficiency for a given resistive load. The proposed WPT rectifier uses feedback to avoid plasma-induced gate-oxide damage and a new dual-supply regulator architecture to achieve high power supply rejection ratio (PSRR) without utilizing any large off-chip capacitors.

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.
