目前集成系统(如微处理器和片上系统)面临的一个主要挑战是功率传输。随着系统规模和复杂性的增加,单个功率域往往需要多个稳压器。这种连接引发了严重的稳定性问题,常常导致系统无用。因此,解决这类系统的稳定性问题具有重大的实际意义。本文提出了一种集中控制器的设计,目的是在不影响其性能的情况下使这种电力输送网络(pdn)稳定。广泛的晶体管级仿真证实了理论结果,并证明该控制器能够以比传统技术更高的面积效率稳定pdn。
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.
