An energy-efficient baseband transmitter design for implantable biotelemetry applications
Bibliographic record
Abstract
Design of implantable wireless telemetry is challenging due to strictly-limited allowable power budgets. The design of wireless prototypes becomes even more challenging due to the need for rice-grain-sized autonomous devices with enhanced useful life. This paper elaborates on the design and implementation of a second-generation prototype of a baseband (BB) transmitter (TX) proposed for use in next-generation body area networks (BANs), with an implementation targeted in TSMC's 65 nm Complementary Metal-Oxide Semiconductor (CMOS) process. The proposed BB TX utilizes a preamble-based asynchronous packet transmission methodology that can potentially meet the energy-efficiency demands of next-generation BANs (below 500pJ/bit). A comparison of the implemented integrated circuit (IC) with the first-generation prototype reveals an improvement of 88% in power consumption. The proposed design requires 1.3mW of power at a supply voltage of 0.9V with an energy efficiency of 144pJ/bit.

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.
