Fully-integrated passive threshold-compensated PMOS rectifier for RF energy harvesting
Bibliographic record
Abstract
This paper presents an RF-DC rectifier for radio frequency energy harvesting applications. The proposed passive multi-stage RF-DC rectifier uses standard PMOS transistors to allow individual bulk biasing without the requirement of deep nwell technology. The RF-DC conversion circuit is based on passive threshold self-compensated topology. A design strategy to enhance the input voltage range and to optimize the power conversion efficiency is presented. Designed and simulated in IBM 130-nm CMOS technology, the proposed 915-MHz rectifier shows improved output voltage and power conversion efficiency compared to recent works. When driving a 1-MΩ load, the RF-DC power conversion unit is able to supply 1-V output with an input power of -22 dBm (6.3 μW) and obtains an efficiency of 11.4% at -16.1 dBm (24.5 μW) while supplying 2-V to the output.

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.
