0.5–1-V, 90–400-mA, Modular, Distributed, 3 × 3 Digital LDOs Based on Event-Driven Control and Domino Sampling and Regulation

This article presents on-chip power delivery hardware comprised of nine event-driven (ED) digital low-dropout voltage regulators (LDOs) for a large digital load. The goal is to address the performance degradations in an LDO’s accuracy and dynamic load regulation in the presence of parasitics in the power grid of a load. In particular, we investigate the effects of power grid resistance (更多
