Resumo(s)
This paper presents and describes switched-capacitor DC-DC combination converters with a single input and multiple outputs, with step-down and step-up voltage ratios. The combination converters provide two or three different DC outputs (depending on the combination), with different conversion ratios. The main advantage of the proposed converters is the low number of components used in the combination (two-output configurations require two link capacitors, and three-output configurations require three link capacitors) and two complementary phase clocks, which may reduce size and manufacturing costs for many applications. The DC-DC combination converters are designed to be fully integrated, and were implemented in a 65nm CMOS technology. The analysis of the proposed configurations for different performance modes and load conditions is presented, and simulation results show that these combination converter topologies are suitable for multiple-output switched-capacitor DC-DC converters with multiple conversion ratios.
