This paper presents a fully integrated capacitive DC/DC-converter with a gearbox type topology. By merging multiple topologies the output voltage range is increased. The dual loop digital control improves load regulation compared with a conventional hysteretic control and reduces ripple under low load operation. The converter was implemented in a 90nm CMOS technology and measurements are presented.
