“…In a practical case, the actual CP output performance is further degraded as it suffers from various power losses during the pumping process. The common loss that is encountered in CP includes redistribution loss [12], conduction loss [32,33], reversion loss [34,35], short circuit loss [36] and switching loss [32]. For low voltage CP, reversion, conduction and switching losses are periodized to be eliminated or minimized as they are the main factors deteriorating the CP performance compared to other losses [37].…”

“…The total power loss due to conduction and switching loss can be minimized if the condition Pconduction = Pswitching is met as depicted in Figure 7. This can be achieved by carefully selecting the optimal transistor width which can be expressed as (4) where Cox and Cov are the oxide capacitance per unit area and the overlap capacitance per unit width respectively [32].…”

“…To mitigate this issue, proper CP improvement techniques such as gate and bulk biasing [32,40,41] are employed for Vth cancellation. For example, the four-phase clock scheme CP with gate boosting techniques and dynamic gate biasing is presented in [40,42] which not only delivers a higher PCE in ultra-low input voltage range (33% and 43.1% @ 100mV Vin), but also reduces the undesirable reverse leakage between the stages.…”

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

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.
