This paper presents a fully self-powered low voltage and low power active rectifier circuit for vibration-based electromagnetic (EM) energy harvesters. A passive AC/DC doubler is used to provide a supply voltage for the active rectifier circuit. The proposed circuit is designed using standard 90 nm TSMC CMOS technology. The simulation results show that the proposed active rectifier circuit has voltage conversion ratio higher than 150% when the input peak voltage is more than 100 mV at open-load condition. The maximum power conversion efficiency of the circuit is 92% with 500 mV input peak voltage and 40 k Omega load resistance. Moreover, the rectifier is able to operate with low frequency input signals commonly available from vibrational energy harvesters.

A Self-Powered and Efficient Rectifier for Electromagnetic Energy Harvesters Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2014-11-05) This paper presents an interface circuit for efficient rectification of voltages from electromagnetic (EM) energy harvesters operating with very low vibration frequencies. The interface utilizes a dual-rail AC/DC doubler which benefits from the full cycle of the input AC voltage, and minimizes the forward bias voltage drop with an active diode structure. The active diodes are powered through an AC/DC quadrupler with diode connected (passive) transistors. The interface system has been validated to drive 22 m...
An electromagnetic energy harvesting system for low frequency applications with a passive interface ASIC in standard CMOS Rahimi, Arian; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2012-12-01) This paper presents a compact energy harvesting system, which consists of an electromagnetic (EM) generator converting ambient low frequency vibrations to DC voltage by using a highly efficient full-wave rectifier in a System-on-Package (Sop). Frequency Up-Conversion technique has been utilized by the in-house EM transducer to harvest energy from very low frequency vibrations (<5 Hz). The interface ASIC is a passive rectifier based on the boot-strap rectification (BSR) technique to decrease the effective th...
A MEMS-based energy harvester for generating energy from non-resonant environmental vibrations Zorlu, Ozge; Külah, Haluk (2013-11-01) This paper presents a non-resonant vibration based electromagnetic MEMS energy harvester, which generates energy from low frequency vibrations with low displacement amplitude. The harvester is composed of an energy harvester chip, housing two electroplated copper micro coils realized on parylene cantilevers and a miniature NdFeB magnet with two mechanical barrier arms. The structure uses the mechanical frequency up conversion (mFupC) principle for energy generation. The non-resonant operation is maintained ...
