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.

Low‐ripple coarse‐fine digital low‐dropout regulator without ringing in the transient state
ETRI Journal, 2020 Herein, a low‐ripple coarse‐fine digital low‐dropout regulator (D‐LDO) without ringing in the transient state is proposed. Conventional D‐LDO suffers from a ringing problem when settling the output voltage at a large load transition, which increases the ...
