Sub-1V Analog LDO Design with Feedback-Driven Optimization
Abstract:
This talk presents the design of an analog low-dropout (LDO) voltage regulator with enhanced performance using feedback theory. Typically, improving analog circuit performance requires significant resources, such as increased power consumption. However, by effectively applying feedback techniques, it is possible to achieve better performance without additional resource overhead. In this presentation, we demonstrate how feedback loops were utilized to enhance LDO performance. Through careful application of negative feedback, we implemented an analog LDO operating at sub-1V with a dropout voltage of only 50 mV. Additionally, the proposed LDO maintains stable operation even under no-load conditions.
