英文摘要	Low noise, fast set-up low-dropout (LDO) regulators are critical for noise-sensitive analog blocks, such as ADCs, PLLs, and RF SoC, etc. This paper presents a two-stage LDO regulator with low output noise, fast set-up, and high power supply rejection ratio (PSRR), based on internal noise filter with a novel fast set-up module, which solves dc shift problems. The proposed LDO is fabricated in a standard 65nm CMOS process. Measurement showed that output noise rms voltage is about 50nV/rtHz ranging from 10Hz to 100 KHz, set-up time is less than 20us, and PSRR is 65B at 1 KHz and 54dB at 1MHz.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000318549000062&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Electrical & Electronic; EI; CPCI-S(ISTP); 0
