In this paper a 90 nm power management circuit for vibration based electromagnetic energy harvesters is introduced to generate 1 V from the rectified DC voltage. A mode selector block is designed to detect the output DC voltage level of the rectifier and adjust the mode of the driver block. In order to set the output to the desired level, a regulation system with negative feedback topology is utilized. The circuit is able to operate with input voltages as low as 0.25 V. The simulation results also show that the power conversion efficiency of the regulated system is almost constant for wide range of input voltages.

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 Self-Powered Rectifier Circuit for Low-Voltage Energy Harvesting Applications
Ulusan, Hasan; Gharehbaghi, Kaveh; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2012-12-05)
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. T...
A wideband electromagnetic micro power generator for wireless microsystems
Sari, Ibrahim; Balkan, Tuna; Külah, Haluk (2007-06-14)
This paper presents a wideband electromagnetic (EM) vibration-to-electrical power generator which can efficiently scavenge energy and generate steady power over a predetermined frequency range. Power is generated by means of electromagnetic induction using a magnet and coils on top of resonating cantilever beams. The reported generator covers a wide band of external vibration frequency by implementing a number of serially connected cantilevers in different lengths. The device generates 0.5 mu W continuous p...
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...
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...
