摘要：
A method is provided. A noise shaped signal having a plurality of instants is generated with each instant being associated with at least one of a plurality of output levels. A next phase is selected for each instant, where each next phase is a circularly shifted phase based at least in part on a previous phase for the associated output level for its instant. A plurality of PWM signals is then generated using the phase for each instant, and an amplified signal is generated from the plurality of PWM signals.
