An adaptable interface circuit for low power MEMS piezoelectric energy harvesters with multi-stage energy extraction Chamanian, Salar; Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Kulah, Haluk (IEEE; 2017-10-21) This paper presents a self-powered interface circuit to extract energy from ambient vibrations for powering up microelectronic devices. The system uses a MEMS piezoelectric energy harvester to scavenge power in 5 μW to 400 μW range. Synchronous electric charge extraction (SECE) technique is utilized to transfer harvested energy to output storage with the help of a novel multi-stage energy extraction (MSEE) circuit. The circuit is optimized in 180nm HV CMOS technology to operate with minimum power losses at ...
An Adaptable Interface Circuit With Multistage Energy Extraction for Low-Power Piezoelectric Energy Harvesting MEMS Chamanian, Salar; Ulusan, Hasan; Koyuncuoglu, Aziz; Muhtaroglu, Ali; Külah, Haluk (Institute of Electrical and Electronics Engineers (IEEE), 2019-03-01) This paper presents a self-powered interface circuit to extract energy from ambient vibrations for powering up microelectronic devices. The circuit interfaces a piezoelectric energy harvesting micro electro-mechanical systems (MEMS) device to scavenge acoustic energy. Synchronous electric charge extraction (SECE) technique is deployed through the implementation of a novel multistage energy extraction (MSEE) circuit in 180 nm HV CMOS technology to harvest and store energy.

An Autonomous Interface Circuit Based on Self-Investing Synchronous Energy Extraction for Low Power Piezoelectric Energy Harvesters ÇİFTCİ, BERKAY; Chamanian, S.; Uluşan, H.; Külah, Haluk (2019-12-04) This paper presents a self-powered interface circuit to rectify and manage the AC output of the piezoelectric energy harvesters (PEH) by utilizing Self-Investing Synchronous Electric Charge Extraction technique (SI-SECE). The system invests charges from the battery to PEH to improve the electromechanical coupling factor and consequently the energy extraction by utilizing only one external component. The circuit was implemented in 180 nm CMOS technology where high voltage (HV) MOS transistors are utilized to...
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...
An Adaptive Converter for Current Neural Stimulators Achieving up to 79% Power Dissipation Reduction Koc, Mert; Chamanian, Salar; Yigit, Halil Andac; ULUŞAN, HASAN; Külah, Haluk (2021-01-01) Power consumption in neural stimulation devices such as cochlear implants, or retinal implants, is an important issue. These devices operate in volume constrained conditions and therefore have a drawback in terms of energy storage. This means that the converters used for the necessary voltage compliance in these devices must be as efficient as possible. This work describes a system implementing an adaptive converter together with a constant current stimulator. The adaptive converter utilizes a three-stage c...
