“…For example, Table 1 shows the average power density of different frequency bands that are commonly used for mobile communication, radio or TV broadcasting, and wireless network [17][18][19]. The mean value of RF energy density in several countries [20][21][22][23][24] with different ranges of average cellular subscription has been plotted in Figure 2 to provide an overview of RF EH feasibility. Theoretically, countries with higher average cellular subscription values tend to have a higher RF energy density due to the higher amount of call traffic and signal transmission.…”

Conventional SC-based charge pump with fixed conversion ratio is predominantly adopted in energy harvesting (EH) systems, which becomes a bottleneck for attaining high power conversion efficiency (PCE) with wide dynamic range (WDR). This article reviews and explores the SC-based reconfigurable charge pump (RCP) as an alternative voltage-boosting element for the EH system. An overview of the RCP structure is established, followed by a comprehensive review of CP reconfigurable topologies along with state-of-art architecture. Design consideration of the RCP in terms of dynamic range, PCE, and VCE is provided to give a clear insight into the future development of RCP architecture for the EH system.INDEX TERMS Energy harvesting (EH), reconfigurable charge pump, wide dynamic range, capacitivebased converter, dc-dc converter, CMOS
