Abstract--A novel voltage regulation scheme to control the
number of multi-phase and frequency for Switched-
Capacitor(SC) DC-DC converters is presented. The
controller adjusts the number of interleaved phases with the
size of switches. In addition, switching frequency of SC DC-
DC converter is increased to reduce output ripple voltage
when output load current is low. 16phase 2:1 SC DC-DC
converter is designed in 45nm standard CMOS process using
