“…Moreover, the proposed circuit maintains more than 20% PCE from −6 to 11 dBm input power range. However, the circuits reported in [18,33] obtain higher PCE at higher input power than this work, while the circuit reported in [19] achieves higher PCE at lower input power in comparison to the proposed work at 2.45 GHz frequency.…”

“…The resultant dc voltage is supplied to full-wave rectifier employing Cockroft-Walton charge pump and Greinacher rectifier. The circuit in [19] presents analysis, modeling, and designing of a cross-coupled rectifier based on a discrete component matching network. Authors in [20,21] report maximum power point tracking (MPPT) technique to maintain high efficiency over extended input power range by selecting optimum number of rectifier stages based on RF input power levels.…”

In this research work, a reconfigurable 2.45-GHz RF-DC converter realized in a 180-nm complementary metal-oxide semiconductor (CMOS) technology is proposed to efficiently harvest electromagnetic energy. The proposed circuit is composed of a low-power path rectifier, a high-power path rectifier, and an adaptive path control (APC) circuit. The APC circuit is made-up of a comparator, two switches, and an inverter. The APC circuit senses the output voltages of the low-power path and the high-power path rectifiers and generates a control signal to automatically switch the proposed circuit between the lower-power path and the high-power path operation depending upon RF input power level. The proposed circuit obtains more than 20% measured power conversion efficiency (PCE) from −6 dBm to 11 dBm input power range with maximum efficiencies of 41% and 45% at 1 and 6 dBm input powers, respectively, for 5 kΩ load resistance. In addition, the proposed circuit shows excellent performance at 900 MHz and 5.8 GHz frequencies.

The usually constrained resources and lossy links scenarios of Internet of Things (IoT) applications require specific protocol suite, as the IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL). Due to its flexibility, RPL can support efficiently vertical applications such as environmental monitoring, smart city and Industry 4.0. In this paper, we propose a new Objective Function (OF) for RPL based on a composite metric considering jointly the residual energy of a node (parent) together with the energy that a neighbor node (child) can transfer to the parent according to the Wireless Power Transfer (WPT) concept. Specifically, we consider simultaneous wireless information and power transfer (SWIPT) technique, which enables both the energy harvesting and information decoding from the same radio frequency (RF) signal, in order to influence the selection of the best path according to the proposed energy efficient metric in RPL. Performance evaluation on a realistic scenario pointed out a remarkable energy saving to prolong the network lifetime, by selecting the best path toward the sink node, with respect to the OFs usually considered in the literature.
