An energy efficient fully integrated OOK transceiver SoC for wireless body area networks
Bibliographic record
Abstract
This work presents a low-power high-speed system-on-chip (SoC) for wireless body area networks (WBANs). The SoC is fully integrated with a 10 Mb/s on-off keying (OOK) RF transceiver, digital processing units, an 8051 micro-controlled unit (MCU), a successive approximation (SAR) ADC, and etc. The receiver adopts envelop detector (ED) based structure to improve the energy efficiency. Conventional ED based structure has a poor sensitivity when reaching a bit rate of Mb/s level. To resolve the problem, we design a receiving (Rx) front-end with 77 dB gain at 10 Mb/s data rate, and propose a novel supply isolation scheme to avoid the instability induced by such a high gain. The transmitter is based on a 2 GHz digitally controlled oscillator (DCO), which uses bond wires as inductors to further reduce the power at transmitting (Tx) mode. The digital baseband is designed by a near-threshold design (NTD) method for low power consumption. The chip is implemented with 0.13 μm CMOS technology, measured results show that the receiver consumes 0.214 nJ/bit at -65 dBm sensitivity, and the Tx energy efficiency is 0.285 nJ/bit at an output power of -5.4 dBm. In addition, the digital baseband consumes 34.8 pJ/bit with its supply voltage lowered to 0.55 V, indicating its energy per bit is reduced to nearly 1/4 of the super-threshold operation.

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.
