A CMOS Broadband Low-Noise Mixer With Noise Cancellation
Bibliographic record
Abstract
This paper presents a broadband low-noise mixer in CMOS 0.13-¿m technology that operates between 1-5.5 GHz. The mixer has a Gilbert cell configuration that employs broadband low-noise transconductors designed using the noise-cancelling technique used in low-noise amplifer designs. This method allows broadband input matching and without the use of inductors that are frequently required in low-noise mixer designs. The current-bleeding technique is also used so that a high conversion gain can be achieved. Measured results show excellent noise and gain performance across the frequency span with an average double-sideband noise figure of 3.9 dB and a conversion gain of 17.5 dB. It has a third-order intermodulation intercept point of + 0.84 dBm at 5 GHz and it is also very compact with the size of the mixer core only being 0.315 mm2.

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.
