Hello,  Froggy,

Would you give more details about your testing method, instrument, and result? I thought it was difficult for those guys who were willing to help you if NOT in the light of your test procedure.


Best regards,

Yawei

Hello Froggy,

typically you design your ADC for a given sampling frequency (or a range of sampling frequencies). In measurement, you sweep the signal frequency over the possible input range up to Nyquist frequency. I am not sure what you mean by "when the ADC sampling frequency increase from low frequency to Nyquist frequency", does it mean you undersample the signal?
