A major challenge currently facing integrated systems, such as microprocessors and systems-on-chip is power delivery. With increasing system size and complexity, multiple voltage regulators are often needed for a single power domain. This connection raises non-trivial stability issues that often render the system useless. It is therefore of great practical interest to tackle the stability of such systems. This brief proposes the design of a centralized controller with the aim of rendering such power delivery networks (PDNs) stable without compromising their performance. Theoretical results are confirmed with extensive transistor-level simulations and demonstrate that the controller is capable of stabilizing PDNs with much greater area efficiency than conventional techniques.

用于片上供电网络的稳定集中控制器

当前集成系统（例如微处理器和片上系统）面临的主要挑战是供电。随着系统尺寸和复杂性的增加，单个电源域通常需要多个稳压器。这种连接会引起非平凡的稳定性问题，这些问题通常会使系统无用。因此，解决此类系统的稳定性问题具有重要的实际意义。本简介提出了集中控制器的设计，目的是在不影响其性能的情况下使此类供电网络 (PDN) 保持稳定。理论结果通过广泛的晶体管级模拟得到证实，并证明控制器能够以比传统技术更高的面积效率稳定 PDN。
