Abstract

fetched live from OpenAlex

Voltage Doubler (VD) rectifiers are known to be most effective in the design of radiofrequency energy harvesting circuits (known as rectenna for Rectifying Antenna). The performance comparisons in most of the previous work have been evaluated concerning single-wave or double-wave bridge rectifiers. However, there are several topologies of VD; this paper then proposes to compare the performance of two types of VD: the Latour VD (LVD) and the Schenkel VD (SVD). Both prototypes are designed with Schottky HSMS 2850 diode, and performances in terms of DC output voltage, conversion efficiency, and matching loss are evaluated. For operating frequencies between 0 and 3.5 GHz, it appears that the performance in terms of DC output voltage and conversion efficiency is almost similar. However, for matching losses, gaps of up to 60 μW/Ω are observed between the two types of VD. This difference can be significant if we consider the level of power consumed in most rectennas applications. The LVD is the topology that shows the least matching loss for input power between -20 dBm and 20 dBm.

Not 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.
