Mixed-signal CPM controlled DC-DC converter IC with embedded power management for digital loads
Bibliographic record
Abstract
This paper presents a novel system and a method for dynamic minimum power point tracking of digital loads in portable applications. The system combines a dc-dc power stage converter IC and the supplied digital load. The dc-dc converter IC employs a mixed-signal current mode (CPM) controller to regulate the supply voltage of an on-chip integrated digital load. The CPM controller is also utilized to obtain information about the input current of the system in real-time, eliminating the need for a dedicated power sensing circuits. The obtained information about the current is utilized by a minimum power point tracking (MiPPT) controller. The MiPPT sets the supply and threshold voltages for the digital load to minimize its power consumption while maintaining a targeted frequency. The dc-dc converter IC, providing 600mW of power, and its digital load IC are fabricated in a 0.13 μm process. Experimental results verify that the introduced system results in up to a 30% lower power consumption.

How this classification was reachedexpand
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.
