An energy-efficient transceiver architecture for short range wireless sensor applications
Bibliographic record
Abstract
A low-power, energy-efficient and configurable transceiver architecture is introduced. It is implemented on a single chip intended for use in short range radios based on WPAN (IEEE802.15.4) at 2.4 GHz. The circuitry employed in the dual conversion receiver with the tunable LNA is re-used in the dual loop frequency synthesizer to form a constant envelope modulator and function as the transmitter; techniques are presented for tuning the center frequency and bandwidth of the LNA, as well as generating the required local oscillator frequencies using injection locking mechanism. The transceiver is fabricated in a 0.18-mum standard CMOS process. The receiver achieves -83-dBm sensitivity and -25 dBm 1-dB compression point. The transmitter outputs -7-dBm QPSK signal, while carrier phase noise is better than -108-dBc/Hz at 5-MHz offset. Active mode power consumption is 11-mW and 14-mW in receive and transmit modes, respectively, on a 1.6-V supply.

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.
