A FLASH TIME-TO-DIGITAL CONVERTER WITH TWO INDEPENDENT TIME CODING LINES
Abstract
We present a time-to-digital converter with a virtual time coding line created as an equivalent of two independent time coding lines operating simultaneously. Proposed solution allows to overcome the technology limitation in achievable resolution and improve the precision of conversion. The new coding line used in the interpolating time counter designed in an FPGA CMOS device provides the precision (standard deviation) below 35 ps within a 1 s measurement range.
