摘要：

A novel time-to-digital converter principle is presented that introduces multisampling capability to the wave union method. The design employs two wave union launchers for both start and stop signals. For test purposes the converter was implemented in Kintex-7 FPGA device (Xilinx). During the initial experimental verification a mean resolution (LSB) of up to 0.7 ps and precision even below 4.7 ps (RMS resolution better than 3.3 ps) were achieved. The design is FPGA logic resource saving comparing to similar solutions but requires much effort during implementation and data encoding.
