该论文提出了一种动态可重构的数字集成电压调节器架构，通过将Buck稳压器与LDO稳压器结合，实现了多域SoC中高效细粒度的动态电压频率缩放（DVFS）。该架构解决了传统Buck稳压器需要大体积无源器件难以集成的问题，同时提升了能量效率。
Regulator (VR) architecture (Fig. 8.3.1), using Buck regulators to each drive a group of Low Dropout (LDO) regulated domains. The domain with the highest Vdd requirement within each group – the critical domain – sets the voltage of its corresponding Buck rail. Such an architecture combines the complementary advantages of Buck and LDO regulators to enable efficient fine-grained Dynamic Voltage and Frequency Scaling (DVFS). Buck regulators [1-7] offer efficient supplyvoltage (Vdd) scaling, but they require bulky passive components which hinder integration and restrict their use to only limited numbers. In contrast, LDOs [8-13] are highly compact but incur significant losses due to the resistive voltage drop across their header devices. Domain grouping is performed at design time to maximize aggregate VR efficiency across
