An efficient integrated interface electronics for electromagnetic energy harvesting from low voltage sources
Ulusan, Hasan; Gharehbaghi, Kaveh; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2013-12-01)
This paper presents a fully-integrated self-powered interface circuit for efficient rectification of the signals generated by vibration based low-voltage electromagnetic (EM) energy harvesters. The circuit utilizes an improved AC/DC doubler structure with active diodes to minimize the forward bias voltage drop for enhancing the rectifier efficiency. The comparators in the active diodes are powered internally by another passive AC/DC doubler with diode connected transistors. The performance is maximized thro...
An efficient hybrid conventional method to fabricate nacre-like bulk nano-laminar composites
Ekiz, O. Oner; Dericioğlu, Arcan Fehmi; Kakisawa, Hideki (Elsevier BV, 2009-08-01)
Bulk nano-laminar composites were fabricated by a novel technique called Hot-press Assisted Slip Casting (HASC) which combines hot-pressing and slip-casting to improve alignment and volume fraction of the reinforcement. Alumina flakes were used as filler in an epoxy matrix. Microstructure of composites and alignment of flakes were characterized by Scanning Electron Microscope (SEM). Three point bending test and Vickers hardness test were done for mechanical characterization of composites. Flexural tests on ...
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 Efficient QAM Detector via Nonlinear Post-Distortion Based on FDE Bank Under PA Impairments
Salman, Murat Babek; Güvensen, Gökhan Muzaffer (2021-10-01)
In this paper, we propose a receiver structure for single-carrier uplink transmission with frequency domain equalization (FDE) that is exposed to power amplifier (PA) nonlinearities. A two-stage approach is adopted, in which linear communication channel is equalized at the first stage, and it is followed by post-distortion, where nonlinear distortion is reduced. In the literature, nonlinear processing techniques are proposed, which perform memoryless compensation of nonlinear distortion together with FDE. H...
