Single-ended impedance-modulation equalization for low-power differential voltage-mode drivers
Bibliographic record
Abstract
In this paper, a modified structure for low-swing voltage-mode drivers in high-speed serial links is proposed, which offers lower static power and reduces the number of transistors compared to the conventional design. This structure adopts an impedance-modulated 2-tap equalizer with analog tap control. The impedance modulation technique is applied to only one input of the driver. Therefore, six transistors are eliminated in the driver and their control impedance circuitry is removed. Simulation results of an 8-Gb/s serial link in a 0.13-μm CMOS technology confirm that the proposed structure reduces the width of the transistors and the static power consumption by 20% and 11%, respectively. Also when a 200 mVp-p differential signal is sent over a channel with 10 dB attenuation at 4 GHz, the eye diagram of the received data has a 113.5 mV eye opening.

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.
