AB  - In this paper, the error re-modulation method for digital correction of pulse width modulation switching amplifier is proposed. This method extracts an error signal from the difference between the reference pulse width modulation signal and power stage output, and generates the error pulse width modulation signal by using a re-modulation method. The error pulse width modulation signal is then used to compensate for the power supply noise and nonlinearity of the power stage. The proposed method is suitable for the correction of the PWM controller in a full digital amplifier.
