The Role of Analog Electronics: From Energy Systems to Food Production

Dear Colleagues,

Analog electronics has long served as the backbone of both power and agricultural technologies. In energy systems, analog circuits ensure accurate sensing, robust power conversion, protection, and monitoring across renewable energy sources, microgrids, and power electronics interfaces. These same foundational principles play parallel roles and are increasingly vital in the agricultural sector, where analog front-end designs enable the precise measurement of environmental variables, soil nutrients, plant physiology, and food quality. As food production systems adopt electrification, renewable energy integration, and autonomous machinery, the synergy between analog energy technologies and agricultural instrumentation becomes more pronounced.

This Special Issue embraces this dual perspective by examining how analog electronics—spanning low-power circuits, sensor interfaces, power management, energy harvesting, and signal conditioning—supports the entire chain from energy generation to crop cultivation, post-harvest monitoring, and food processing. This Special Issue will showcase contributions from researchers working at the intersection of electronics, energy systems, and agricultural technology to illustrate how analog innovations enable a more sustainable and technologically integrated food–energy ecosystem.

Topics of particular interest include, but are not limited to, the following:

• Analog and mixed-signal circuits for renewable energy systems, including photovoltaic, wind, and bioenergy applications;
• Analog front-end designs for agricultural, biological, and food-quality sensors;
• Signal conditioning circuits for soil, plant, and environmental monitoring;
• Power electronics, conversion, and protection systems supporting agricultural electrification;
• Low-power analog and mixed-signal architectures for remote and autonomous field-deployed systems;
• Energy-harvesting and power-management circuits for distributed sensing in agriculture;
• Analog instrumentation for drones, UGVs, and greenhouse monitoring;
• Analog interfaces for biosensing, nutrient detection, and plant health assessment;
• Integrated analog–energy solutions for climate-smart agriculture;
• Case studies demonstrating analog circuit applications across food production, processing, and storage;
• Analog electronics supporting IoT/edge-computing systems for food and energy sustainability.
