Abstract
This paper proposes a new flash time-to-digital converter (TDC) design, which incorporates deterministic, variable delay into the decision elements. These are implemented with cross-coupled NAND standard cells of variable transistor widths. Both experiment and simulation are used to validate this new design, which provides variable time-difference ranges by controlling the input slew rate. It is also possible to use the proposed flash TDC as a soft macro.
