A Fast-Transient All-Digital LDO with Adaptive Clock Technique [PDF]
Electronics, 2019 To get a better tradeoff between the transient performance and current efficiency of Digital Low-Dropout (DLDO) regulator, this paper proposes an all-digital Low-Dropout (LDO) regulator with adaptive clock technique. The sample clock is supplied by a proposed digital oscillator (DOSC) whose output frequency can be changed seamlessly.
