Abstract	The design and development of low-power electronics for implantable leadless pacemakers present significant engineering challenges due to strict power, size, and longevity constraints. This article explores key aspects of low-power circuit design, power management, and energy-efficient communication to enhance the operational lifespan of these devices. We discuss power constraints in leadless pacemakers, emphasizing energy efficiency strategies such as ultra-low-power microcontrollers, analog front-end design, and memory optimization. Power management architectures, including ultra-low quiescent current regulators, dynamic voltage scaling, and power gating, are analyzed to minimize energy consumption. Additionally, low-power wireless telemetry solutions, including Bluetooth Low Energy and MICS band communication, are evaluated for their impact on power efficiency. We also address low-power sensing and stimulation circuitry, optimizing ECG and intracardiac electrogram acquisition while maintaining effective pacing pulse generation. The potential of energy harvesting technologies, such as piezoelectric and electromagnetic methods, is explored as a complementary power source. Furthermore, biocompatibility and long-term reliability considerations are examined to ensure device longevity. Finally, emerging trends, including AI-driven power management and advanced semiconductor technologies, are discussed as future directions. This work provides a comprehensive overview of state-of-the-art low-power design strategies for leadless pacemakers, contributing to their advancement in clinical applications.
