“…Therefore, a number of CMOSbased power conditioning circuits (e.g., converters, rectifiers, etc.) for energy harvesting have been reported, including those allowing multiple energy sources as the input (Camarda et al, 2018;Katic et al, 2018;Li et al, 2018b;Liu et al, 2018a,b,c;Luo et al, 2018;McCullagh, 2018;Shi et al, 2018;Taghadosi et al, 2018;Wang et al, 2018;Yi et al, 2018a,b;Yoon et al, 2018).…”

Energy harvesting is one of the most rapidly growing of the emerging technologies. This field has arrived at the hybrid and multi-source era, where hybrid structures and novel materials are able to boost the energy conversion efficiency and/or make the harvesters capable of benefitting from multiple energy sources simultaneously. Such hybrid and multi-source energy harvesters have not frequently been reviewed in the past, potentially because of the small number of publications compared to that of their single-source and individual counterparts. However, as their number is becoming larger, it is now necessary to give sufficient and frequent reviews of developments in the field. Furthermore, an increasing number of developed energy harvesters are moving out of the laboratory into industrial markets. In practice, energy harvesters need to be integrated with energy storage and/or end users such as sensors and wireless sensor networks. Therefore, the harvester-storage and harvester-sensor integration systems also need to be reviewed frequently. This mini review includes works reported in the first half of 2018 and provides a timely update to the published review. It focuses on the abovementioned hybrid and multi-source energy harvesters as well as on integrated harvesters, energy storage systems and end users (e.g., sensors), including CMOS (complementary metal-oxide-semiconductor) technology-based harvesters and systems.

“…In the recent decade, the demand for miniaturized ultralow-power (ULP) wireless sensor nodes (WSNs) [1,2], medical implants [3], and wearable devices [4] for the Internet of Things (IoT) [5] are gaining momentum in academic and industrial research. Power consumption of ULP analog-frontend (AFE) and transceivers are ever decreasing, prompting the use of energy harvesting (EH) as an alternative solution to batteries where their replacement is a constraint and impractical for implantable devices.…”

“…This is due to the effectiveness in design for low start-up and promotes high power conversion efficiency (PCE) compared to the capacitive-based counterpart (chargepump). Recently, it has been demonstrated that capacitivebased step-up DC-DC converters are becoming competitive in effective start-up and improved PCE performance for EH applications [5,6]. However, there are only limited development of capacitive-based CMOS step-up DC-DC converters implemented in RFEH systems [11][12][13][14][15].…”

Bulky off-chip inductors are predominantly adopted for inductive-based step-up DC-DC converter in RF energy harvesting (RFEH) systems, which impose a restriction in physical form factor for miniaturized device. This paper review and explores the capacitive-based step-up DC-DC converters (charge-pump) as voltage boosting element for low-voltage RFEH systems. An overview of RFEH is established and a comprehensive review of CMOS charge-pump is followed along with the complementary frequency generation circuit used as a clocking element. Key design considerations of charge-pump circuits are included here along with recommendations to circumvent its bottlenecks for future development in RFEH systems. INDEX TERMS-RF energy harvesting (RFEH), charge-pump, capacitive-based converters, DC-DC converter, CMOS.

“…The Dickson charge pump has been modified to reduce the leakage current with linear regulator and thereby total power consumption can be reduced [6]. Another Dickson charge pump based rectifier with improved performance in two configurations are presented which works in GSM band with a satisfactory PCE [7]. Also dynamic threshold reduction technique based CMOS rectifier has been designed with the use of a clamper to reduce the effective threshold voltage and increase the sensitivity and hence achieving a high PCE [8].…”

- The development of latest generation of wireless communication standards in the recent years has created enormous possibility to deploy high speed wireless network throughout the globe. There is always demand for high speed, seamless data connectivity. But it is a well-known fact that the increase in speed always makes the power consumption higher. Also while attempting to cater to the need of connectivity to a remote location, the major bottleneck is the availability of power. Hence incorporating self-sustainability to a wireless network is becoming the need of the hour. Radio frequency (RF) energy harvesting (EH) is gaining much attention in contemporary communications in this context. In the design of an EH system, the high frequency rectifier plays a significant role. Apart from several design hurdles that exist in a high frequency rectifier, to attain a high percentage conversion efficiency (PCE) at lower input power is the primary design challenge. This paper presents a design of a modified transmission gate (TG) based high frequency rectifier with two substrate voltage compensation techniques, viz. capacitor and MOS based compensation for RF EH system.The proposed capacitor and MOS based techniques enable the rectifier to achieve a PCE upto 86% and 92% at -5dBm respectively in its single stage implementation. This can be claimed to be the highest in-class efficiency as compared to recently published works. The frequency responses with both the techniques depict a wide band performance covering all popular wireless bands. The dynamic power dissipations (DPD) observed are 12nW and 16nW at -5dB, whereas the leakage power (LP) is 20x10-51W and zero respectively. Further such an performance are obtained using minimal number of transistors, viz. 4 and 5 respectively.
