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.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
