Abstract
This paper presents an all-digital switched-capacitor DC-DC converter with a Switch Logic Controller and Optimizer (SLCO) that converts the battery voltage (3.6 V nominally) into an output voltage of 1V. The SLCO achieves the maximum efficiency while keeping the output voltage ripples and load regulation at minimum values. The SC converter is implemented in 0.13 μm CMOS technology using thick oxide I/O devices and achieves a maximum efficiency of 68% at power density of 0.12 W/mm2. The SC converter delivers up to 100 mA load current. Output voltage ripples and load regulation are less than 16 mV and 0.02 %/mA, respectively.
