A study on split-output TSPC CMOS circuits
Bibliographic record
Abstract
In this paper, we present a heuristic study of a class of CMOS true single-phase clocked circuits (TSPC). TSPC circuits have proven to yield good performances at high frequencies. The proposed method may speed up design by identifying technology insensitive circuit properties. Our study focuses on split-output circuits which are believed to yield better performances than the other single-phase clocked circuits. We also present a characterization of the performances of these circuits as a function of load with NORTEL 0.8 /spl mu/m CMOS technology. With realistic (nonideal) Hspice simulated netlist extracted from layout, we observed that the maximum operating frequency for split-output was 1.17 GHz. It is shown that the maximum speed of TSPC latches obtained with our simple suboptimal design method does not directly decrease with loading as in static gates. Finally, the speed degradation of the studied circuit with degraded clocks is characterized.

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; both teacher heads agree on what is shown here.
