The voltage multiplier (VM) circuit is a cascade arrangement designed from a series of rectifiers to obtain high DC output voltage. In this classical approach, the DC voltage which is getting generated in the present stage contributes to the next stage. This phenomenon is recurring at every stage resulting into higher DC output voltage than previous. The proposed signaling scheme enables the use of the rectified DC voltage/stage in a classical way along with the involvement of instantaneous input RF voltage. As a result, higher output DC voltage and improved power conversion efficiency (PCE) will be achieved as compared to a conventional VM circuit signaling scheme. The conventional VM circuit used in this work was designed by stacked series arrangement of three standard differential drive rectifiers. Similarly, the proposed VM circuit was formed by implementing proposed signaling scheme into the conventional VM circuit. These architectures were implemented in a standard 0.18 lm CMOS technology The measurements were done by using input RF signal frequency of 433 MHz for resistive load values of 30, 100 KX, and 1 MX respectively. The measured results show that the proposed VM scheme has 22-32 % better power conversion efficiency than the conventional VM scheme.

RF signal carries very low amount of energy and can be easily dissipated as heat loss. Threshold voltage and leakage current that are inherent in MOS transistors significantly affect the performance of an RF AC to DC converter. A device with bulk connected to its drain improves the threshold voltage and leakage current. This work designs the half-wave and full-wave AC to DC converters with devices' bulk connected to source and devices' bulk connected to drain. The designs used the native devices in TSMC 0.18 micron CMOS technology, and were simulated using transient analysis in different process corners and operating temperatures. In simulations, the RF signal was represented by a sinusoidal input of 900 MHz frequency and of 390 mV amplitude. The sizes of transistors and the number of stages, of each converter, that resulted to highest power efficiency were determined via circuit simulations. The optimal design was a four-stage half-wave AC to DC converter with devices' bulk connected to drain, which produced a DC output of 2.7 V with 37.42 % efficiency at 100 kilo ohm load.

“…Many researches focus on modifying present rectifier and voltage multiplier topologies to achieve higher gain, sensitivity, efficiency [52,[55][56][57]61]. For instance, the voltage multiplier achieved maximum 11% PCE at −24 dBm (4 µW) in [62] and 41% PCE at −20.6 dBm (8.7 µW) input power in [57]. While the majority of publications utilized 0.18 µm CMOS technology in their work, [52] applied commercial 40 nm CMOS process to build a low-voltage operation voltage multiplier that reached 44% PCE at 390 mV input.…”

Wireless power transmission was conceptualized nearly a century ago. Certain achievements made to date have made power harvesting a reality, capable of providing alternative sources of energy. This review provides a summ ary of radio frequency (RF) power harvesting technologies in order to serve as a guide for the design of RF energy harvesting units. Since energy harvesting circuits are designed to operate with relatively small voltages and currents, they rely on state-of-the-art electrical technology for obtaining high efficiency. Thus, comprehensive analysis and discussions of various designs and their tradeoffs are included. Finally, recent applications of RF power harvesting are outlined.
