Hi all,

I am trying to use DFT to get the THD of my design.
But somehow the output waveform give only a input frequency component and some of its harmonics with the same magnitude. ( I used Hspice to verify that the DFT result should not be like that.)

can anyone tell me how to fix it ?

Thanks.

Best Regards,
whlinfei
 

A picture is worth a thousand words! Could you show your DFT plot and its parameters?
