FPGA as an ADC
Hi guys,
I am designing a circuit that will convert 12V signal into digital through a Comparator and that needs to be read by FPGA.
(1) If I don't use a common GND for the comparator and the FPGA, do I have to use Differantial inputs?
(2) Which IO Standard do I use, and where can I get their specifications
(3) Can someone advise me on VHDL code for the FPGA to read this data and use it as an input.
Regards
AR
