PSR Enhancement Through Super Gain Boosting and Differential Feed-Forward Noise Cancellation in a 65-nm CMOS LDO Regulator

This paper presents a 65-nm CMOS low-dropout (LDO) regulator employing a super gain amplifier (SGA) and differential feed-forward noise cancellation to maximize the power supply rejection (PSR). The SGA in the error amplifier is augmented by a positive feedback current mirror, and this SGA boosts th...
