High-Resolution Time-to-Digital Converters (Tdcs) with a Bidirectional Encoder
SSRN Electronic Journal, 2022 A high-resolution time-to-digital converter (TDC) based on wave union (four-edge WU A), dual-sampling, and sub-TDL methods is proposed and implemented in a 16-nm Xilinx UltraScale+ field-programmable gate array (FPGA). We combine WU and dual-sampling techniques to achieve a high resolution.
