A Fully Integrated Digital LDO With Adaptive Sampling and Statistical Comparator Selection 150 150

Abstract:

Digital LDOs are gaining attention for their operation with small output capacitance. Adaptive sampling with a large frequency scaling ratio is required for fast transient response with low-power operation. Furthermore, the design of a fluctuation detector to deal with large load steps is important. This letter describes an adaptive-sampling digital …
