Suggest options for FPGA or any other simple ways. Thanks and regards Itp

Any scheme like digitizing of time or time to amplitude (voltage) conversion (TAC) technique with a time resolution of 1ns are acceptable . Regards Itp

Recently, I found a couple of papers which use FPGA to make a time to digital converter with a 200ps resolution, using tapped delay lines. Trans, On Instrumentation Vol46 No1 Feb1997.
