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.
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?
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
