On Secrecy Energy Efficiency of RF Energy Harvesting System
2019 IEEE International Workshop on Signal Processing Systems (SiPS), 2019The increasing use of information source in unreliable wireless communication is a driving force to explore the networks’ energy efficiency and security. To fully improve the performance of the system, in this paper, we combine these two directions and investigate the secrecy energy efficiency (SEE) of the network in which the information can be ...

CMOS voltage regulator for RF energy harvester
2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS), 2015We present initial experimental results of our low-power RF energy harvester that includes a charge pump, voltage regulator and a bandgap voltage reference in CMOS 130nm technology. The DC regulator designed for RF IC energy harvesting applications and optimized for powering implantable electronics.

Characterization of RF energy harvesting at 2.4 GHz
2017 24th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2017This paper presents a comprehensive study on RF energy harvesting process at a frequency of 2.4GHz using P21XXCSR-EVB evaluation board from Powercaset. The study is carried out by considering several types of antennas, varying distances from the transmitting source at different input and output power values. The maximum distance at which the harvesting

Waveform-aware ambient RF energy harvesting
2014 IEEE International Conference on RFID (IEEE RFID), 2014In this paper we suggest a new class of RF energy harvesters, which we call “waveform aware harvesters”. In contrast to traditional rectenna designs, which are usually designed for high efficiency with continuous wave (CW) signals, waveform aware harvesters are RF to DC converters which are optimized for their performance with non-CW signals.

A Survey Study of Different RF Energy Sources for RF Energy Harvesting
2019 International Conference on Automation, Computational and Technology Management (ICACTM), 2019Radio Frequency (RF) energy conversion and harvesting topologies gains much attention that promises to operate the low power devices. The base of any RF energy harvesting model is the selection of appropriate RF souce followed by other three main stages which include receiving antenna, converting into DC output and utilisation of that output in any low-

Improved Harvested RF Energy for Cyber-Physical Energy Systems
2019 IEEE Globecom Workshops (GC Wkshps), 2019Cyber-physical systems need to harvest renewable energy sources to work properly. Energy harvesting comes from sources such as solar radiation, ambient RF, wind, rain, or vibrations. RF energy can be harvested in the dark, or when no solar energy is available.
