Are wave union methods still suitable for 20 nm FPGA-based high-resolution (< 2 ps) time-to-digital converters?

The proposed TDCs combined the advantages of 1) our newly proposed sub-tapped delay line (sub-TDL) architecture effective in removing bubbles and zero-bins and 2) the wave union (WU) A method to improve the resolution and reduce the impact introduced from ultrawide bins.
