Hi, I have given a project in which I need to design an ADC for GNSS (Global Navigation Satellite System). Here are some of specifications of the ADC. input frequency fin = 20MHz Bandwidth = 20MHz Power consumption P <= 1mW ENOB >= 3.7 Resolution: 4 bits
I am confused which sampling frequency should I choose? I know it has to be larger than two times highest frequency component but I don't know which frequency optimistic, 40MHz, 60MHz, 80MHz, 100MHz, or larger. And what type of ADC is more appropriate for this application?
