Abstract
A fully integrated low-voltage RF receiver front end for 5 GHz radio applications, implemented in a standard 0.18 μm CMOS technology, is presented. The receiver consists of a differential low noise amplifier, an active mixer, and a quadrature voltage-controlled oscillator. The complete receiver is packaged in a standard 24-pin ceramic flat pack and consumes 56 mW from a 0.8 V supply. Measurement results show that the receiver has an overall noise figure of 7 dB, a −1 dBm input-referred IIP3, and 22 dB of image rejection. A stand-alone single-ended version of the LNA is also presented. Simple mechanisms for tuning the gain and the centre frequency of the LNA are proposed. With a supply voltage of 1 V, the LNA provides a power gain of 13.2 dB, has a noise figure of 2.5 dB, and over 10 dB of gain control and 360 MHz of frequency tuning. The LNA still operates well from a supply voltage as low as 0.7 V, providing a power gain of 7 dB.

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
