Abstract—Implementing efficient and cost-effective power
regulation schemes for battery-powered mixed-signal SoCs is
a key focus in integrated circuit design. This paper presents a
fully-integrated switched-capacitor DC-DC converter in 45 nm
digital CMOS technology. The proposed implementation uses
digital capacitance modulation instead of traditional PFM and
PWM control methods to maintain
