title: Design methodology in multiphase buck converter based on minimum time control for high efficiency RF amplifiers

abstract: This paper proposes an interleaved multiphase buck  converter with minimum time control strategy for envelope  amplifiers in high efficiency RF power amplifiers. The solution of  the envelope amplifier is to combine the proposed converter with  a linear regulator in series. High system efficiency can be  obtained through modulating the supply voltage of the envelope  amplifier with the fast output voltage variation of the converter  working with several particular duty cycles that achieve total  ripple cancellation. The transient model for minimum time  control is explained, and the calculation of transient times that  are pre-calculated and inserted into a look-up table is presented.  The filter design trade-off that limits capability of envelope  modulation is also discussed. The experimental results verify the  fast voltage transient obtained with a 4-phase buck prototype.
