Abstract:
1. A Traveling Pulse Wave Quantizer (TPWQ) comprising: a fast delay line having an input to accept a first stop signal followed by a second stop signal, the fast delay line comprising a first plurality of first delay elements connected in series with an output between each first delay element, where each first delay element has a first time delay; a slow delay line having an input to accept a clock signal and comprising a first plurality of second delay elements connected in series with an output between each second delay element, where each second delay element has a second time delay greater than the first time delay; a sampler comprising a first plurality of clocked buffers connected in series with a sample output between each clocked buffer, each clocked buffer having a signal input connected to the output of a corresponding first delay element, and a clock input connected to the output of a corresponding second delay element; and, a resampler having an input to accept the first plurality of clocked buffer outputs, and an output to supply a first plurality of time-to-digital converter (TDC) output bits representing a time delay between the first stop signal and a first period of the first clock signal, regardless of a duration in delay between the first stop signal and the second stop signal.
