Standing-wave transmission-line-resonator VCO for E-band Applications
Bibliographic record
Abstract
In this paper, a fully integrated 42-GHz VCO in 90 nm CMOS is described. This VCO is designed for use in licensed E-band (i.e., 81-86 GHz) transceiver systems. In contrast to conventional LC-VCO topologies, a standing wave transmission line resonator instead of a lumped LC tank is employed to provide an extended output frequency range and relatively low phase noise. A slow wave coplanar waveguide (CPW) structure was used as the transmission line to reduce conductor and radiation losses and to minimize substrate attenuation. Both simulation and chip measurements show good VCO performance. Wide tuning range (1.7-GHz) and low phase noise (-102-dBc/Hz at 1MHz) were achieved. The paper also discusses design criteria and testing strategies.

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.
