Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a new architecture for envelope-tracking power supplies for base stations. The proposed multiphase DC-DC converter circuit uses multiple switching circuits (as well as a voltage follower circuit), each optimized for a different envelope frequency, to realize both high efficiency and wide bandwidth. The operation of the circuit, and simulation results, are described.
