Abstract
Continued advancements in state-of-the-art integrated circuits have furthered trends toward higher computational performance and increased functionality within smaller circuit area footprints, all while improving power efficiencies to meet the demands of mobile and battery-powered applications. A significant portion of these advancements have been enabled by continued scaling of CMOS technology into smaller process node sizes, facilitating faster digital systems and power optimized computation. However, this scaling has degraded classic analog amplifying circuit structures with reduced voltage headroom and lower device output resistance; and thus, lower available intrinsic gain. This work investigates these trends and their impact for fine-grain Low-Dropout (LDO) Voltage Regulators, leading to a presented design methodology and implementation of a state-of-the-art Ringamp-Assisted, Output Capacitor-less Analog CMOS LDO Voltage Regulator capable of both power scaling and process node scaling for general SoC applications.
