A High-Voltage UWB Pulse Generator Using Passive Amplification in 65-nm CMOS
Bibliographic record
Abstract
This paper proposes an ultra-wideband (UWB) pulse generator featuring high output amplitude for applications with long transmission and detection range. The output signal of a switch-mode power amplifier stage is passively amplified by a wideband matching network to produce output voltage amplitudes beyond the supply voltage level. Incorporating the parallel LC load of the power amplifier into the matching network and considering the constraints of the wideband matching when the power amplifier is ON and OFF, only a 2-section matching network is added for wideband matching. Employing a trapezoidal waveform as the input signal of the power amplifier, the design flexibility of the matching network to generate a regulation-compliant UWB pulse is further extended. Implemented in a 1-V 65-nm CMOS process, the proposed UWB pulse generator produces a UWB pulse with a de-embedded peak-to-peak amplitude (Vpp) of 2.49 V, a bandwidth of 6.8 GHz and pulse duration of 0.5 ns achieving 249% peak-to-peak to supply voltage ratio.

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.
