Abstract

A modulator having a pulse density modulator configured to generate from bit stream information a Pulse Density Modulation (PDM) stream based on a PDM clock; and a bit stream adjuster configured to divide the PDM clock into a PDM multi-phase clock, adjust a duration of at least one pulse of the generated PDM stream by selecting a PDM clock phase of the PDM multi-phase clock for sampling the generated PDM stream, and output an adjusted PDM stream.
