A Temperature-stable 60-dB programmable-gain amplifier in 0.13-µm CMOS
Bibliographic record
Abstract
A programmable-gain amplifier (PGA) for in- vehicle power-line communication (PLC) is implemented in 0.13-μm CMOS. The PGA robustly operates over the extended automotive temperature range of -55°C to +125°C. A transconductance boosting technique is employed to improve the linearity of the amplifier. Post-layout simulation results confirm that the amplifier achieves a gain range of 0 to 60 dB, while the variation of each gain setting is less than 0.3 dB when the temperature changes from -30°C to +80°C, and is less than 0.9 dB when the temperature changes from -55°C to +125°C. The P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1dB</sub> of the PGA at its minimum gain is 2.5 dBm, and the -3-dB bandwidth of the circuit at its maximum gain is 90 MHz. The PGA consumes less than 9.0 mW from a 1.2 V supply.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
