A Coarse-Fine Time-to-Digital Converter

A design of time-to-digital converter (TDC) using a coarse-fine conversion scheme is presented. The coarse stage was accomplished by a delay line, and used a loop counter at the end of the delay line to achieve wide dynamic range. The fine stage utilized the dual DLL structure to achieve high precis...

With an input reference clock of 125MHZ, the TDC achieves 8ps resolution, and the dynamic range achieves 1.5μs.https://doi.org/10.1051/itmconf/20171108006
