Abstract

fetched live from OpenAlex

Modeling and analysis of a coupled three-stage ring oscillator is presented in this paper. The oscillator consists of two ordinary three-stage ring oscillators, which are coupled to each other and oscillate with the same frequency, but with 30 degree phase difference resulting in three sets of quadrature outputs. A simple and insightful technique for modeling coupled oscillators is proposed here. This technique is then used to analyze the coupled oscillator. It has been proven analytically that the coupled two rings, oscillate with the same frequency, but with 30 degree phase shift. It has also been shown that for small transistor sizes, the coupled ring oscillator has an inherent capability of oscillating with frequencies as high as 1.577 times that of a single ring. The accuracy of the proposed linearized model is verified with SPICE simulations.

Teacher imitation

Not 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.
