Low-Power Design refers to techniques and strategies used in electronics to minimize power consumption while maintaining performance. This approach is crucial for battery-operated devices, such as smartphones and wearables, where energy efficiency extends battery life and enhances user experience. Engineers employ various methods, including optimizing circuit design, using energy-efficient components, and implementing power management techniques. By focusing on low-power integrated circuits and dynamic voltage scaling, designers can significantly reduce energy usage, making devices more sustainable and cost-effective over time.
