I am designing a 4 bit ADC sampled at 1Ghz. When I apply an input sine wave of 500Mhz, and do SNDR calculation, I get a very low SNDR(~10 db) giving an ENOB of less than 2.
I have seen in many ADC papers where they apply an input which is at the nyquist frequency, yet still achieve a high SNDR and ENOB.
How is this possible?
