Fully differential, 40 Gb/s regulated cascode transimpedance amplifier in 0.13 µm SiGe BiCMOS technology
Bibliographic record
Abstract
A broadband differential Transimpedance amplifier (TIA) has been designed and measured in 0.13μm BiCMOS Technology. Regulated Cascode (RGC) configuration has been employed to reduce the effect of the large parasitic capacitor of the PIN diode. The added CPD, representing PIN diode parasitic capacitor, is 300fF. The TIA has 53.6 dBO differential transimpedance gain and 28GHz measured bandwidth. The total measured integrated input referred noise is 6.11μArms. The TIA chip including the TIA and 3 stages of buffer consumes 110mW power from a 3V power supply. The active chip area is 330μm×210μm and the total chip area including the pads is 1050μm×530μm.
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.
