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 P1dBof 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 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.
