Ultra wide-band high-order pulse digital transmitter IC in 90nm CMOS for biomedical radar sensing
Bibliographic record
Abstract
In this paper, an UWB transmitter for next generation bio-radar sensing system characterized by a high data rate, low area, low power consumption, and low complexity, and specifically designed to fit Canada UWB spectrum mask, is proposed for real-time bio-medical sensing. The transmitter is based on an all digitally controlled circuit pulse generator in 90nm CMOS to generate the tenth-order derivative of Gaussian pulse with bi-phase modulation scheme operating in the 6–10GHz band specified by Canada draft spectrum specification. The switch diplexer presents a 0.5dB insertion loss. The transmitter core occupies an chip area of 200um×140um. Simulating on a 1V voltage supply, the transmitter draws average 9.037mW when generating the tenth-order Gaussian derivative pulses at a pulse repetition frequency of 50MHz. The transmitter has an output power of 7.08dBm and each pulse carries an energy of 3.1pJ.The pulse is digitally synthesized and bi-phase modulated. This transmitter prototype can generate any other pulse combinations with minor design modifications. The predicted performance of the bio-radar is also evaluated and discussed.

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.
