Hi IvoI'm feeling so amazed, that u have a designed a class D amplifier with no ripple. Could you tell me what have u done, please?I have made it for last six month, and still find some ripple in the output. I have no distortion meter to measure that distortion. But I can tell u that I use a single order Butterworth filter at the output stage, and pole-zero compensation as loop filter to compensate the distortion. Anyone could give me suggestion with that?Regards
