Low-Power Circuits for a 2.5-V, 10.7-to-86-Gb/s Serial Transmitter in 130-nm SiGe BiCMOS
Bibliographic record
Abstract
Low-power building blocks for a serial transmitter operating up to 86 Gb/s are designed and implemented in a 130-nm SiGe BiCMOS technology with 150-GHz SiGe fTHBT. Design techniques are presented which aim to minimize high-speed building block power consumption. They include lowering the supply voltage by employing a true BiCMOS high-speed logic family, as well as reducing current consumption by trading off tail currents for inductive peaking. A serial transmitter testchip consuming under 1 W is fabricated and operation is verified up to 86 Gb/s at room temperature (92 Gb/s and 71 Gb/s at 0degC and 100degC, respectively). The circuit operates from a 2.5-V supply voltage, which is the lowest supply voltage for circuits at this data rate in silicon technologies reported to date.

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.
