I am designing a time interleaved at 800MHz. The interleaving factor is 4. Therefore each sub-ADC should work at 200 MHz.
Input frequency is 200MHz. Now the question is to find SNDR of the sub-ADC at 200MHz.
The problem is if I apply this frequency i would get a dc output. So, I chose a frequency near to the 200MHz such as 199.912MHz (using coherent sampling). Then I got SNDR.
Is this the correct way?
Thanks in advance
