Design and analysis of a compact UWB pulse generator with programmable pulse shape
Bibliographic record
Abstract
We present a programmable ultra-wideband (UWB) pulse generator designed and simulated in 90 nm CMOS technology. The design receives an input square pulse and uses a pulse-combinatorial method to generate an output pulse composed of six individual impulses, each independently adjustable in both amplitude and delay. Additionally, the final pulse width can be adjusted. The design uses a 1.2 V supply and is compact (core area ~0.1 mm2). A digital memory block is used to retain the control bits that describe two different pulse shapes for purposes of demonstrating binary modulation schemes, including phase-shift keying, pulse-position modulation, or pulse-shape modulation at rates up to 2 Gbps. The design can produce pulses respecting the FCC-defined UWB indoor frequency mask, and consumes about 54 mW at the peak data rate, representing a pulse efficiency of 27 pJ/pulse.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
