Strategic Management of Power Management Integrated Circuits (PMIC) in Mixed-Signal SoCs: Enhancing Efficiency and Minimizing Noise

This paper explores the strategic management of Power Management Integrated Circuits (PMICs) within Mixed-Signal System-on-Chip (SoC) architectures, with a focus on enhancing efficiency and minimizing noise. As mixed-signal SoCs become increasingly complex and prevalent in various applications, the role of PMICs in managing power distribution efficiently while minimizing noise interference is critical to maintaining overall system performance and reliability. This study reviews the challenges associated with PMIC design, including the intricacies of integrating analog and digital components, the need for advanced power conversion techniques, and the impact of process variations on circuit behavior. It discusses advanced techniques for efficiency improvement and noise reduction, such as multi-phase buck converters, dynamic voltage scaling, and layout optimization. Furthermore, the paper analyzes strategic management approaches in the development process, highlighting the importance of project management, design-for-test methodologies, and the optimization of power delivery networks. The paper combines theoretical analysis with practical design considerations, supported by experimental results, to provide a comprehensive framework for managing the complexities of PMIC design in mixed-signal environments, ultimately aiming to enhance system-level performance in modern electronic applications.
