IN 2023, we continued hard working to deliver high-quality\nand interesting research reports from the authors in diverse\nfields of electronics to our readers. I also use the opportunity\nto remind the research community that we recently announced\na call for papers for special issue on Advances in Artificial\nIntelligence for Healthcare, which can be found on the website\nof the journal. Therefore, I invite all potential authors, whose\nresearch covers topics related to the special issue, to submit\ntheir work. The tentative publication date of the issue is\nOctober 2023.<\/h5>\n&nbsp\n
In this issue we published four papers, each focused on a\ndifferent field of electronics, as I already mentioned above.<\/h5>\n&nbsp\n
In the first paper, entitled \u201cNovel Renewable Energy Source\nin Standalone Microgrid Application with Island Load Mana-\ngement,\u201d authored by M. Teke, M.\u00d6. Yatak, and E. S. Y. Ya-\nseen, a thermoelectric generator that uses hot water from the\nhot spring area to generate free electricity as a new renewable\nenergy source in a microgrid application is proposed. The\nmain advantage of the described approach reflects in gene-\nrating electricity from renewable sources (photovoltaic and\nthermoelectric) without wasting energy by controlling loads\naccording to the proposed load management algorithm. The\nmicrogrid and energy management control is modeled with\nMATLAB\/Simulink and the results show that the essential load\nis always active through thermoelectric generator even in the\nabsence of battery storage system.<\/h5>\n&nbsp\n
The second paper, entitled \u201cFault Coverage Improvement\nof CMOS Analog Circuits Using Supply Current Testing\nMethod,\u201d by A. Arabi, M. Ayad, M. Benziane, N. Bouro-\nuba, and A. Belaout, brings in a testing technique, based\non supply current verifying, for fault detection of analog\ncircuits containing CMOS operational amplifiers. The testing\nmethod is based on the over-sighting of the quiescent supply\ncurrent (Iddq) of the CMOS operational amplifier operating\nin its quiescent mode and the supply current of the CMOS\noperational amplifier when it is used as a Sallen-Key band\npass filter in the AC and transient operating domains. The\nauthors demonstrated that the proposed method achieved 100%\nclassification accuracy for the case of bridging faults, whereas\nthe fault coverage ratio attained 57.14% for all open faults\ninjected in the two circuits under test. By using different\nmachine learning classifiers, the authors managed to increase\nthe coverage of open faults from 57.14% to 66.7%.<\/h5>\n&nbsp\n
In the third paper, \u201cEfficient Modulo Multiplier,\u201d authors\nR. U. Ahmed, S. D. Thabah, M. Haque, and P. Saha, presented\na methodology for computing modulo multiplication with a\nmoduli set 2n, 2n\u22121, 2n+1. In addition, they proposed designs\nof the modulo multipliers based on half-adders, full-adders, 4:3\ncompressor, 7:3 compressor, and multi-column compressor 5,\n5:4. The designs are implemented using VHDL and simulated\nusing Xilinx 14.2 design suite on Virtex-6 device to estimate\ndelay, power consumption, and power-delay-product. Moreo-\nver, the same designed circuits are simulated in Cadence RC\ncompiler using 0.18 \u00b5m technology to estimate the area. The\npresented results showed 66.34% improvement in terms of area\nfor the case of the modulo 2n \u2212 1 multiplier of 4-bit operand\nsize when compared with the best design reported by other\nauthors. In addition, the modulo 2n + 1 multiplier of 4-bit\noperand size demonstrated improvement of 58.59% in terms\nof area and improvement of 22.72% for 8-bit operand size in\ncomparison to the best design reported in other papers.<\/h5>\n&nbsp\n
Final paper, \u201cCompact Ultra-Wideband Planar Inverted F\nAntenna on Laminated Paper-Based Substrate with Reduced\nSpecific Absorption Rate,\u201d by S. Kumari and V. R. Gupta,\ndeals with a laminated paper-based Planar Inverted F Antenna\n(PIFA) for wireless body area network (WBAN) applications.\nAs reported by the authors, the measured specific absorption\nrate of the proposed antenna is 0.64 Watt\/kg, which is much\nbelow the SAR radiation safety guidelines. Moreover, the\ndesigned antenna has a group delay lesser than 2.3 ns, which\nindicates better phase linearity and the maximum measured\npeak gain of 9.53 dB (free space) and 6.07 dB (on-body).\nThus, it is an ideal antenna for a wireless body area network\nas it can serve multiple applications.<\/h5>\n&nbsp\n
As always, I thank the authors for their contribution to\nthis issue of the journal and send great appreciation to all\nthe reviewers who participated in the editorial process by\nproviding valuable comments in timely manner to the editors\nand authors.<\/h5>\n
