The present disclosure provides for a time to digital converter (TDC). The time to digital converter can include a reference ingress that receives a reference signal and passes the reference signal through multiple delay elements, a clock signal ingress that receives a clock signal and passes the clock signal through another set of delay elements, and multiple comparators, which are fewer in number than the total number of delay elements. The multiple comparators 1) receive the delayed reference and delayed clock signals and 2) output a set of comparison results for comparisons of pairs of delayed references and delayed clock signals.
