Dear all,
I am trying to calculate the SNHR of the pipelined ADC in Cadence. Its a 12-bit ADC with sampling rate 40 MSPS. I tried to calculate the SNHR of the input signal close to 9MHz and i got an SNHR of about 70dB. But when I increase the frequency of the input signal to around 11MHz, the SNHR drops by almost 20 dB. I am unable to understand this behavior. Could someone please explain as to why this can be happening?
Thanks,
Chinmaye
