WebNov 25, 2024 · High-PSR and fast-transient LDO regulator with nested adaptive FVF structure Abstract: This paper presents a low-dropout (LDO) regulator using nested adaptive flipped voltage follower (FVF) to achieve fast-transient response and improve both power supply rejection ratio (PSR) and line regulation. WebFig. 2 presents the block diagram of the proposed LDO. Loop 1 consists of a Folded Flipped Voltage Follower (FFVF) driving an output FVF stage. Loop 1 by itself can regulate the output voltage but exhibits poor load regulation owing to its low loop gain. The low output impedance of the FVF stage provides a high unity gain frequency (UGF) for ...
