Abstract
Flip-flops (FFs) are an essential component of digital circuits, yet they use a lot of power and energy. This paper introduces the VLFF, an extremely low-power flip-flop that operates with just two single-phase clock transistors. The extracted simulation results show that VLFF is the most power-efficient FF amongst all examined FFs for the data activity (DA) range of 0% to 45%. Test-chip measurement results for the test-chip designed in TSMC CMOS 65 nm gp PDK demonstrate that at VDD = 1 V, power consumption is reduced by 63% and 16% with 12.5% DA, and 52% and 6% with 25% DA in comparison to TGFF and 18TSPC, respectively. • This paper proposed a very low-power flip-flop with only two single-phase clock transistors. • Proposed flip-flop is the most power-efficient amongst all considered. state-of-the-art flip-flops for data activities in the range of 0 – 45%. • Test-chip implemented in TSMC 65nm GP PDK validates the power savings of the proposed flip-flop over 18TSPC, and TGFF.

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 it
