A low drop-out (LDO) regulator with a feed-forward ripple cancellation (FFRC) technique is proposed in this paper. The FFRC-LDO achieves a high power-supply rejection (PSR) over a wide frequency range. Complete analysis and design steps of the FFRC-LDO are presented in this paper. Kelvin connection is also used to increase the gain-bandwidth of the LDO allowing for faster transient performance. The LDO is implemented in 0.13 m CMOS technology and achieves a PSR better than 56 dB up to 10 MHzdoi:10.1109/jssc.2009.2039685 fatcat:jnh7sr7ftvafzeefpdnhdret2e
