Design and Electronic Interfacing of FR4 and Polyimide PCB-based Electromagnetic Resonating Micro-mirrors

by Nikolai Dimech, Ivan Grech, Russell Farrugia, Owen Casha, Barnaby Portelli and Joseph Micallef

Advances in Science, Technology and Engineering Systems Journal, Volume 11, Issue 1, Page # 1–10, 2026; DOI: 10.25046/aj110101

Abstract:

This paper presents the design and fabrication of an electromagnetically actuated PCB-based resonating scanning micro-mirror for LiDAR applications, with optimization targeted towards low-cost fabrication and a high scanning angle. Traditional silicon MEMS-based micro-mirrors, while offering high precision and compatibility with CMOS processing, are limited by fragility at low scanning frequencies and costly fabrication processes. To…

Essential Features/Issues of a Multi-Phase Switching Synchronous Buck Regulator

by Hani Ahmad-Assi, Nour Sultan Gammoh and Mariana Awni Al Bader

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 5, Page # 1056–1063, 2020; DOI: 10.25046/aj0505130

Abstract:

This paper addresses essential features/issues and proposes solutions that would improve the overall performance of a multi-phase buck converter. Low efficiency at light load is addressed with phase shedding, load fast transient and regulated output voltage spiking/dipping is addressed with novel helper technique at the point of load (output node). An Integrated current sensing is…
