This paper presents a 2/3 step-down switched-capacitor DC-DC converter with integrated NMOS-LDOs in both charging and discharging phases to suppress the output voltage ripple. A gate driving technique implementing adaptive gate slope and gate pre-charge is proposed to reduce the switching noise duri...
