Abstract
A multiphase switching voltage regulator is disclosed. The regulator includes a first clock generator circuit configured to receive a reference clock, and to generate M first clocks, where the M first clocks are phase separated by 360°/M, a plurality of phase extrapolator circuits, where the plurality of phase extrapolator circuits includes N phase extrapolator circuits, and a phase selector multiplexer configured to provide one of the M first clocks to each of the phase extrapolator circuits, where the N phase extrapolator circuits are configured to generate N output clocks, where the N output clocks are phase separated by 360°/N.
