28nm CMOS Technology-Based Ultra-Compact Tunable IR-UWB Transmitter for Neural Implants: Compliance With FCC, ECC, and Japanese Spectral Masks under IEEE 802.15.6
Bibliographic record
Abstract
This paper introduces a novel tunable oscillator-based impulse radio ultra-wideband transmitter, implemented in 28 nm HPC TSMC CMOS technology. The transmitter employs a differential ring voltage-controlled oscillator to achieve wide tuning across low and high-frequency bands, ensuring compliance with FCC, ECC, Japan's spectrum masks, and IEEE 802.15.6 standard. Operating at a data rate of 40 Mbps, it features low power consumption below 1 mW and an ultra-compact design footprint of just 0.0019 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>, making it ideal for neural recording implants. The transmitter achieves energy efficiencies of 2.75% and 1.52% in the lower and upper bands, respectively, with output power of approximately -15 dBm and -17.8 dBm. Additionally, it attains a Figure-of-Merit of 17.4 and 9.5 (1/ mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>) in the upper and lower bands, respectively, highlighting its superior area and power efficiency.

How this classification was reachedexpand
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.
