Within this area, we focus on the design and implementation of compact and energy-efficient power management circuits and systems for next-generation electronic applications. This includes ultra-low-power DC–DC converters for embedded and IoT platforms, as well as energy-harvesting interfaces that enable long-term and maintenance-free operation. The research combines analog precision with digital adaptability through mixed-signal regulation techniques, allowing efficient and intelligent energy control under varying operating conditions. Design challenges such as conversion efficiency, integration density, and dynamic response are carefully addressed to achieve optimal performance in highly compact and low-power systems. The developed solutions are applicable to a wide range of technologies, from autonomous IoT sensor nodes and biomedical devices to wearable and energy-harvesting platforms.
