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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
