ディジタルLDO

Power and supply management is a critical component that directly affects the energy efficiency and reliability of the system. Supply management is becoming more complex and power-hungry as we try to integrate more functional blocks into the same chip. In this research, we aim to develop digital LDOs that can quickly adapt to load activity without needing external signals and clocks. We are now focusing on using analog circuits to assist digital operation. The key is to ensure that the analog component is minimal and does not compromise the merits of digitization of power MOSFETs. We are adopting techniques with the self-adapting capability to tackle PVT variation.
