Abstract

fetched live from OpenAlex

The accuracy issues of on-wafer noise characterization for a linear noisy two-port are presented in this paper. It starts with the description of a microwave noise measurement system and the possible source of error due to the microwave power meter in the measurement system. With the description of noise characterization techniques, this paper reviews a couple of methods for noise parameter extraction to handle the errors in the measured noise powers, noise factors, and source admittances. It also presents the methods to extract the physical noise parameters and to take care of different source admittances in the hot and cold states for accuracy enhancement.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
