A 204GS/s 1-to-2 Analog Demultiplexer in 22nm FDSOI CMOS
Bibliographic record
Abstract
A 204GS/s 1-to-2 analog demultiplexer (ADEMUX) is reported with a measured bandwidth of 60 GHz and a hold-mode isolation $\gt20 \mathrm{~dB}$ up to 67 GHz. It operates with rail-to-rail sampling clock signals up to at least 102 GHz, the highest in CMOS. A SFDR of 32 dB was measured for $11 \mathrm{GHz}, 600 \mathrm{mV}_{\text {ppd }}$ sinusoidal inputs sampled with a 64 GHz clock. Large signal operation was demonstrated by demultiplexing a 92 GBaud ($184 \mathrm{~Gb} / \mathrm{s}$) PAM-4 input into two 46Baud PAM-4 output streams sampled on opposite phases of the 46 GHz clock signal. The data path of the ADEMUX consumes 48 mW from 0.8 V, while the power consumption of the clock amplifier is 109 mW from 0.8 V and 1.2 V supplies.

How this classification was reachedexpand
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.
