Special Section on Low Power Wireless Transceivers

Low-power wireless transceivers have become ubiquitous due to their extensive use in energy-limited applications such as the Internet of Things (IoT), body area networks, wireless communication systems, sensor nodes, and high-accuracy localization and ranging systems. As many of these devices rely on batteries with limited energy capacity, minimizing power consumption is essential for extending operational lifetime. In biomedical applications, additional requirements, such as including constraints on size, thermal performance, and biocompatibility, must be considered. Moreover, certain biomedical devices are powered wirelessly, which demands the development of innovative low-power circuit techniques and energy-efficient system design approaches. These transceivers frequently operate in environments with significant interference, necessitating the design of low-power, blocker-tolerant circuits that maintain high performance while supporting increasing data rates. Effectively addressing these challenges requires a cross-layer design approach that encompasses precise system modeling, robust design methodologies, energy-efficient circuit implementations, advanced power management techniques, and seamless system-level integration.

This special issue covers all aspects of systems and circuits of low power radios, including but not limited to: low power analog and digital circuit design, low voltage and sub-threshold circuit operation, low power transceiver architectures,  blocker tolerant low power transceivers, low power design techniques for biomedical signal conditioning circuits, sensor interfaces and stimulators, energy harvesting and power management solutions for implantable and wearable biomedical devices. Submissions should present ideas that are prototyped and verified through silicon measurements to demonstrate practical feasibility and performance benefits. Both original research articles featuring novel circuits and systems and in-depth review papers highlighting state-of-the-art techniques and future research directions in energy-efficient biomedical electronics are strongly encouraged.
