1. A device comprising a time-to-digital converter (TDC), the TDC comprising:
a first input;
a second input;
a delay line coupled to the first input and comprising a plurality of first delay elements coupled in series, each of the plurality of first delay elements having a first delay time;
a second delay line comprising a second delay element, the second delay element having the first delay time and coupled to the second input;
a third delay line comprising a third delay element, the third delay element having a second delay time and coupled to the second input, the second delay time being smaller than the first delay time;
a first set of arbiters, each arbiter in the first set of arbiters having a first input coupled to one of the plurality of first delay elements of the delay line and having a second input coupled to the second delay element; and
a second set of arbiters, each arbiter in the second set of arbiters having a first input coupled to one of the plurality of first delay elements of the delay line and having a second input coupled to the third delay element.
