Abstract

fetched live from OpenAlex

We compare two designs for dual power supply RF-powered systems such as implantable stimulators and contactless smartcards. Specifically, we compare a traditional design using a step-up DC/DC converter versus a design that uses a step-down converter. We analyze which system can operate from a lower input source voltage, and show how non-idealities in DC/DC converters affect the relative merits of the step-up versus step-down designs. We demonstrate that the step-down architecture can increase maximum operable link distance and power available to the load in systems with high source resistances or inefficient DC/DC converters. Through simulation and experiment, we verify that source resistances greater than 250k/spl Omega/ are possible in RF-powered systems, and that step-down converters can improve available load power by 100%.

Full frame distilled prediction

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.
