“…Generally, off-chip inductors have larger Q-factor compared to on-chip inductors. As an example, with an off-chip inductor with a Q-factor that is four times higher compared to an on-chip inductor, the voltage gain is increased by a factor of two in comparison to its on-chip counterpart [37]. Hence, the Q-factor of the IMN inductor plays a significant role in enhancing the sensitivity performance of the RFEH system by boosting VAnt to drive the transistors of the rectifier in improving the operation.…”

“…The Q factor of an on-chip inductor is dependant on parasitics which is proportional to the technology node [38]. Nevertheless, there are various techniques reported in improving the Q-factor through the physical design innovation of on-chip inductors [37,39,40] and high-Q co-design antenna [10,41] to attain superior performance in sensitivity. Table I summarizes the Q-factor of various inductors.…”

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.

In this article, a voltage doubler circuit designed using 28 nm FD‐SOI technology has been studied for electromagnetic energy harvesting. NLVT transistor type is chosen and used as a diode for the realization of a Dickson voltage doubler circuit. Moreover, the impact of back gate polarization on circuit performance has been analyzed. The optimization of the circuit along with the measurement results has been presented (1.19 V for 1 stage at −26.3 dBm @ 2.45 GHz).

“…The idea is to make the devices to harvest the available surrounding power and transfer to the electrical power which can be stored in the battery. There are a lot of power energy sources lies around us such as radio frequency (RF), vibration, solar, wind and thermal [1][2][3][4][5]. Up to date, the present energy harvesting only generates small electrical power, which depends on technique and concept used in the system.…”

Abstract. This paper presents a 900-2400 MHz AC-DC rectifier circuit for radio frequency (RF) energy harvesting. The proposed circuit consists of a rectifier and charge pump. The multi-stage NMOS RF-DC rectifier circuit is designed to convert the AC signal to DC signal while the charge pump helps to amplify the DC amplitude. The proposed circuits are designed and simulated using CMOS 0.13-µm technology. The simulation results show that the proposed circuit able to produce 2.9 V DC voltage at 10 kΩ load with an input voltage of 150 mV.
