title = "A 2.45-GHz RF energy harvester with on-chip 8-VCR SC booster for IoT devices",
abstract = "This paper presents an efficient RF energy harvester with reconfigurable voltage conversion ratio (VCR). The system adopts an optimal combination of multi-stage differential drive cross-coupled (DDCC) rectifiers and an on-chip switched-capacitor (SC) booster capable of providing 8 VCRs. The proposed system and its post-layout simulation in 65nm CMOS process verify that the output voltage of 1 V can be generated from 2.45-GHz RF signals with input power of - 20.1 dBm, while the SC booster achieves the power conversion efficiency (PCE) up to 68.3%.",
