A fully integrated CMOS transmitter design for IR-UWB communication systems
Bibliographic record
Abstract
A fully integrated CMOS impulse-based transmitter with on-off keying (OOK) modulation scheme, for ultrawideband (UWB) impulse radio (IR) system has been designed in a standard TSMC 0.18μm CMOS technology. A novel Gaussian mono-pulse generator using simple and robust design method has been presented. On-chip pulse shaping using LC Band-Pass Filter (BPF) is developed to meet the Federal Communications Commission (FCC) spectrum requirement. The proposed UWB transmitter has been laid out and post-layout simulation results are analyzed. A Gaussian mono-pulse of less than 100 ps falling/rising time with a 130 mVpp amplitude was observed, at a clock frequency of 500 MHz. The total power dissipation of the transmitter is 1.2 mW with only 316 μW consumed by impulse generator. The output of the transmitter is 48 mV <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pp</inf> under a 1.2 V power 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.
