A Low-Power Dual-Injection-Locked RF Receiver With FSK-to-OOK Conversion for Biomedical Implants
Bibliographic record
Abstract
We present in this paper an ultra low power ISM band RF receiver intended for implantable biomedical devices. The proposed circuit, which represents the reception part of a new energy-efficient RF FSK transceiver, consist of an FSK receiver (Rx) with OOK fully passive wake-up device (WuRx). This WuRx is batteryless with energy harvesting technique which plays an important role in making the RF transceiver energy-efficient. This proposed receiver is achieved with a reduced hardware architecture which does not use an accurate local oscillator, high Q external inductor and I/Q signal path. The circuit is base on a dual injection locked FSK-to-ASK conversion technique. The circuit is implemented in IBM 0.13 μm CMOS technology with 1.2 V supply voltage. This WuRx achieves a data rate of 100 kbps for 0.2 μW power dissipation at -53 dBm input signal. The Rx shows -78 dBm sensitivity for 8 Mbps data rate while consuming 639 μW power.

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.
