Design and Development of Power-Efficient Digital Circuits for IoT Applications

This Special Issue presents research focused on the development of Ultra-Low-Power (ULP) Integrated Circuits (ICs) designed to operate within stringent power budgets, aiming to reduce reliance on batteries. These advancements are critical to enabling the Internet of Things (IoT), where interconnected devices exchange data to improve quality of life.[14] The increasing adoption of Internet of Things (IoT) devices has amplified the need for digital circuits that operate with minimal power consumption. As many IoT systems are battery-powered and deployed in remote environments, power efficiency has become a critical design requirement. This paper explores the design and development of power-efficient digital circuits suitable for IoT applications. Key techniques such as clock gating, power gating, and dynamic voltage scaling are discussed. A case study of a digital interface for a temperature sensor is presented, demonstrating notable reductions in both dynamic and leakage power. Simulation results validate the proposed strategies, showing that significant power savings can be achieved without adversely affecting performance. These methodologies offer scalable solutions for future energy-conscious IoT system designs.
