Abstract
A low-power FM demodulator operating across a 2-10-GHz IF bandwidth for its application in wideband heterodyne receivers is presented. A four-stage ring oscillator locks to one-fourth of the input FM, thereby reducing the energy required for wideband demodulation. The measurements show that the oscillator is capable of locking to at least a modulating frequency of 400 MHz, and further testing is limited by the FM source. Linear demodulation of the quadrature-phased outputs is realized using a low-power folded CMOS mixer, even as the fractional bandwidth of the input FM approaches unity. The inductorless 65-nm CMOS prototype occupies 0.17 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and dissipates 3.2 mW from 1.2 V at the quiescent point. The measured SNR sensitivity is 8 dB and the demodulator bit-error rate is 0.1% at 10 Mb/s for a 45-mVpp input signal at IF.

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.
