Abstract
This paper describes the design of an inductor-less variable-gain amplifier cell with a bandwidth over 15 GHz. A high bandwidth is maintained even when the amplifier cells are cascaded, for example in implementing a limiting amplifier. The amplifier cell is implemented using a modified Cherry-Hooper architecture that utilizes active negative feedback to obtain a variable gain from -4 to +17dB for 16 cascaded cells, and an adjustable bandwidth from 9GHz to 15GHz per cell with a nominal bandwidth of 12.4GHz. By avoiding the use of broadbanding techniques, such as peaking inductors, area is greatly reduced. The optimized amplifier cell occupies an area of 93/spl mu/m by 42/spl mu/m, and is critically damped to limit peaking to 0dB.

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 it
