“…However, on-chip impedance matching network suffers from low Q-factor for the inductor and capacitor due to high losses in the substrate [135]. To address this issue, several work in employing off-chip inductor and capacitor are proposed [70], [127], [128], [129], [130], [131], [132], [133], [134]. Reference [127] proposed a novel impedance matching network with a 1:100 transformer and a single LC matching network.…”

“…Reference [127] proposed a novel impedance matching network with a 1:100 transformer and a single LC matching network. Reference [128] proposed two external SMD inductors as the matching network and fine-tuned it to match at dual frequencies of 900 MHz and 1.8 GHz. Reference [129] proposed a 900 MHz and 2.4 GHz dual-band impedance matching network built from two L-matching networks.…”

“…These methods can be adopted for multiband energy harvesting schemes. For instance, [128], [131], and [134] proposed a multiband RF-DC rectifier with threshold voltage selfcompensation to reduce the reverse leakage current. The proposed technique would improve the performance of the CCDD-type rectifier for multiband energy harvesting.…”

The increasing demand for wireless Internet of Things (IoT) calls for power efficient RF energy harvesting approach. The current dominant single-band RF energy harvesting front-end system restricts itself to a single frequency, which is at the risk of ineffective operation when the harvesting frequency is unavailable. This paper reviews and explores the alternative approach of a multiband RF energyharvesting front-end system. It covers all essential circuitry of a multiband RF energy harvesting front-end system, starting from the recent RF surveys which investigate the typical, usable, and high-strength RF input, to the overview of the state-of-the-art antenna, impedance matching network (IMN), and RF-DC rectifier. The recent advancement of the multiple RF input harvesting abilities, reflection loss minimization, and performance improvement are comprehensively reviewed for different operating conditions, and this review also presents the advantages and disadvantages of the different circuit architecture combinations for multiband RF energy harvesting front-end systems. In summary, this review aims to fill the research gap in the further advancement of multiband RF energy harvesting towards enhancing its performance through optimal circuit integration of the front-end system.INDEX TERMS CMOS, power conversion efficiency (PCE), multiband RF energy harvesting, RF power transmission.
