Performance of a 12GHz monolithic microwave distributed oscillator in 1.2V 0.18μm CMOS with a new simple design technique for frequency changing
Bibliographic record
Abstract
A monolithic distributed oscillator (DO) is designed and fabricated using an n-FET-based Traveling Wave Amplifier (TWA), coplanar waveguides (CPW) and a proposed coplanar bend structure called a ‘folded CPW’. The measured loss S21 (dB) of the ‘folded CPW’ is 1.259dB at 10GHz before pad de-embedding. Experimental measurements are reported for the first time for a DO using an industry-standard 0.18μm CMOS technology, (with a bias of 1.8V). The oscillator operates at 12.0GHz with 5.77dbm and the measured phase noise is –115.16dBc/Hz at 1MHz offset. The signal power in the harmonics is very low, -34dBm in the 2nd harmonic. The frequency of oscillation can be increased for this oscillator by 170MHz by varying the dc bias. Finally, a technique to change the frequency by varying the intercell inductive loads is proposed.
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.
