This paper presents the design of a new threshold compensation technique for UHF Dickson rectifiers. The proposed solution addresses the efficiency reduction of previous architectures especially under large input powers. The measurements show that the proposed technique achieves very good efficiency within 10 dBm variation of the input power. Therefore, the technique is suitable for applications where the incident power is not constant. Thanks to the reduction in the reverse leakage current, a peak efficiency of 34% at 433 MHz was measured.

Threshold Compensated UHF Rectifier With Local Self-Calibrator Gharehbaghi, Kaveh; Zorlu, Ozge; Kocer, Fatih; Külah, Haluk (2017-06-01) This letter presents a threshold-compensated UHF rectifier with a local self-calibrator in a 0.18-mu m CMOS process. The self-calibrator compensates the intrinsic-V-th voltage for a broad range of input power intensity to decrease the sensitivity of the rectifier's power conversion efficiency (PCE) to the input power fluctuations. This makes the structure suitable for wireless charging applications, where efficient RF-to-DC conversion at different RF intensities is required. The proposed circuitry includes ...
Optimization of Power Conversion Efficiency in Threshold Self-Compensated UHF Rectifiers With Charge Conservation Principle Gharehbaghi, Kaveh; KOÇER, FATİH; Külah, Haluk (2017-09-01) This paper presents a compact model for threshold self-compensated rectifiers that can be used to optimize circuit parameters early in the design phase instead of time-consuming transient simulations. A design procedure is presented for finding the optimum aspect ratio of transistors used in the converter and number of rectifying stages to achieve the maximum power conversion efficiency. In the presented analysis, the relation between the power conversion efficiency and the load current over the variation o...
Optimization of AA-Battery Sized Electromagnetic Energy Harvesters: Reducing the Resonance Frequency Using a Non-Magnetic Inertial Mass Yasar, Oguz; Ulusan, Hasan; Zorlu, Ozge; Sardan-Sukas, Ozlem; Külah, Haluk (2018-06-01) This paper presents an optimization study for a miniature electromagnetic energy harvester, by incorporating a non-magnetic inertial mass (tungsten) along with the axially oriented moving magnets. The aim is to decrease the operation frequency and increase the output power of the harvester with the usage of higher density material and larger magnetic flux density. Dimensions of the magnets are optimized according to the harvester dimensions and magnetic flux gradients. Additionally, coil length, width, resi...
A vibration-based electromagnetic energy harvester system with highly efficient interface electronics Rahimi, Arian; Zorlu, Özge; Muhtaroǧlu, Ali; Külah, Haluk (2011-09-01) This paper presents a vibration-based electromagnetic (EM) energy harvester system utilizing novel and highly efficient interface electronics. The energy harvesting module up-converts the environmental low frequency vibrations for increased AC power output. The interface circuit employs a boot-strap technique to reduce the threshold voltage of the rectifiers further increasing the power conversion efficiency of the overall system. The complete system, composed of an energy harvester module, and a compact 0....
A 180 nm Self-Powered Rectifier Circuit for Electromagnetic Energy Harvesters Ulusan, Hasan; Zorlu, Ozge; Külah, Haluk; Muhtaroglu, Ali (2013-12-18) This paper presents a new self-powered low voltage rectifier implementation for vibration-based electromagnetic (EM) energy harvesters. The proposed circuit is an improved version of the previously reported rectifier, which was designed in TSMC 90 nm CMOS technology. The circuit is designed in lower cost UMC 180 nm CMOS technology, and uses a passive AC/DC quadrupler structure to supply the external power of the utilized active components. Simulation results show that the maximum power conversion efficiency...
