THE BASED ON FPGA DIGITAL CONVERTER OF ONE-HOP TIME INTERVALS
The circuit building principles of the interpolating time-to-digital converter having sub-nanosecond resolution and simple realized project of converter based on Xilinx FPGA. Due to the direct interval counting using the scale of multiphase ring oscillator the converter kernel possesses reduced “dead” time and high resolution that is determined by delay time of logical gate. The 50 ps resolution is reached in device version using Virtex 7 matrix.
