Abstract

fetched live from OpenAlex

This paper presents a new RF notch filter topology for image rejection in heterodyne receivers. The circuit is combined with a cascode low noise amplifier (LNA) and an output buffer for testing purposes. It is implemented with standard CMOS 0.18/spl mu/m technology. The notch filter is tunable from 10.5 to 11.1GHz. Up to 10dB controllable gain is obtained from the LNA in the pass band at 6.5GHz. A -50dB image rejection is realized by using on chip inductor Q-factor enhancement techniques. At the maximum in band gain of 12dB and -50dB image rejection, the circuit consumes 22mW of power with a noise figure of 2.4dB, a -12.5dB IIP3, from a 1.5V power supply.

Not 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.
