A differential 160 MHz self-terminating adaptive CMOS line driver
Bibliographic record
Abstract
High-rate data communication over cable requires a line driver capable of providing the power gain necessary to transmit the modulated signal over the low characteristic impedance of the cable. For a fully-integrated transceiver, the line driver must be designed using CMOS technology. For best performance, a line driver must have a differential topology, no loss in the termination, a tunable output impedance and a voltage gain independent of process and load impedance variation. This topology is capable of driving 2 V/sub pp/ across 75 /spl Omega/ from a 3.3 V supply with <-47.5 dB total harmonic distortion and 160 MHz bandwidth. The target application is the full-duplex transmission of up to 622 Mb/s over 300 m of coax cable using a multilevel modulation scheme and hence a bandwidth requirement of 160 MHz.

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.
