چکیده

This paper deals with linear behavior and distortion of class-D amplifier. calculation approach and effective terms on the distortion of amplifier is also carried out. the typical circuit of class-D amplifier CMCD is considered. Traditional approaches have been analyzed the distribution amount in class-D amplifier in voltage mode (VMCD) simulation result has been compared with mathematical approaches of amplifier. This comparison validate the effectiveness of mentioned terms on third harmonic distortion amounts.
