分布式片上电压调节是解决当今高端SoC中电源完整性问题的重要手段。然而，由于系统的规模和调节器与大型负荷网络之间复杂的相互作用，确保由多个电压调节器监管的大规模输电网络的稳定性是具有挑战性的。我们提出了一个理论上优雅的框架，为网络稳定性提供了严格的保证。我们进一步发展了一种实用的设计方法，该方法在很大程度上将线性电压调节器的设计从复杂负载的设计中解耦出来，使得确保整个网络的稳定是可行的。所提出的设计方法已成功地应用于几个设计实例，保证了稳定性和具有竞争力的性能。
Distributive on-chip voltage regulation is appealing to solving the power integrity problems in nowadays high-end SoCs. Nevertheless, ensuring the stability of large-scale power delivery networks regulated by a multiplicity of voltage regulators is challenging due to the size of the system and complex interactions between the regulators and the large loading network. We present a theoretically elegant framework that provides a rigorous guarantee for network stability. We further develop a practical design approach that largely decouples the design of linear voltage regulators from that of the complex load, making it feasible to ensure the stability of the complete network. The presented design approach has been successfully applied to several design examples with guaranteed stability and competitive performances.
