Review ArticleOpen accessIn the author namesReview of Charge Pump Topologies for Micro Energy Harvesting SystemsMichelle Lim Sern Mi, Md. Shabiul Islam, Jahariah Sampe, Sawal Hamid Md. AliThis paper reviews CMOS based charge pump topologies used within autonomous embedded micro-systems. These charge pump structures have evolved from its simplistic diode-tied, single-branches with major threshold drops to exponential type, dual-branches with sophisticated gate and substrate control for lower voltage operation. Published charge pumps are grouped based on architecture, operation principles and pump optimization techniques with their pros and … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 26 May 2016 · 7,630 accessesView PDFCite
Review ArticleOpen accessIn the author namesArchitecture of an Ultra-Low-Power Fully Autonomous Universal Power Conditioner of Energy Harvester for Wireless Sensor Networks: A ReviewYeo Kim Heng, Md. Shabiul Islam, Susthitha Menon et al.A fully autonomous Universal Power Conditioner (UPC) that can accept energy from any micro-energy harvester (e.g., photovoltaic, thermoelectric, electromagnetic, piezoelectric etc.) is proposed. Generally, UPC removes the need of multiple optimized source specific converters. But, the proposed UPC architecture will be Ultra-Low-Power (ULP) with maximized efficiency to support the low energy levels generated by harvesting sources. This UPC uses a … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 28 Mar 2016 · 7,786 accessesView PDFCite
Review ArticleOpen accessIn the author namesArchitecture of Ultra Low Power Micro Energy Harvester Using RF Signal for Health Care Monitoring System: A ReviewFarah Fatin Zulkifli, Jahariah Sampe, Muhammad Shabiul Islam, Mohd Ambri MohamedThis research presents architecture of Ultra Low Power (ULP) Micro Energy Harvester (MEH) using Radio Frequency (RF) signal as an input. RF has many advantages compared to other ambient sources because it is not affected by changes of weather or time, does not require heat or wind exposure and it can be moved randomly within the bound of the transmission … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 7 Jul 2015 · 6,961 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Novel Architecture of Maximum Power Point Tracking for Ultra-Low-Power Based Hybrid Energy Harvester in Ubiquitous Devices: A ReviewMichelle Lim Sern Mi, Sawal Hamid Muhammad Ali, Md Shabiul IslamThis research work presents a novel architecture of an Ultra-Low-Power (ULP) based Hybrid Energy Harvester (HEH) consisting of multiple input sources such as kinetic, thermal and solar energy, harvested from passive human power. Having multiple ambient sources mitigates limitations caused by single sources especially for bodily-worn applications; however, this results in impedance mismatch among the different integrated sources. To overcome … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the author namesOn-Chip Implementation of Pipeline Digit-Slicing Multiplier-Less Butterfly for Fast Fourier Transform ArchitectureYazan Samir Algnabi, Rozita Teymourzadeh, Masuri Othman et al.Problem statement: The need for wireless communication has driven the communication systems to high performance. However, the main bottleneck that affects the communication capability is the Fast Fourier Transform (FFT), which is the core of most modulators. Approach: This study presented on-chip implementation of pipeline digit-slicing multiplier-less butterfly for FFT structure. The approach taken; in order to reduce computation complexity … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 8,016 accessesView PDFCite

Research ArticleOpen accessIn the author namesOrthogonal Frequency Division Multiplexing Timing Synchronization in Multi-Band Orthogonal Frequency Division Multiplexing Ultra-Wideband SystemsAymen M. Karim, Md. Shabiul Islam, Masuri OthmanProblem statement: MB-OFDM UWB systems have attractive features and received a great attention. It has the capability of sending/receiving data at rates in access of 100 Mbits sec-1. Owing to the sensitivity of OFDM systems to synchronization errors, a fast synchronization algorithm is required to discern for the start of OFDM symbol. Existing approaches to OFDM time synchronization rely on … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,426 accessesView PDFCite
