Abstract
Recent digital low-dropout regulators have demonstrated competitive load regulation performance for a digital load even with a low input voltage. However, few existing regulator designs have investigated into supporting a spatially large load with realistic grid parasitics. This paper presents a system consisting of nine digital low-drop-out regulators based on event-driven control for better supporting such load. At 0.5V (1V) input, our prototype improves the load regulation FoM by 3.9X (9.1X) and current density by 8.7X (2.8X) over the prior state of the arts [1, 3, 4].
