Abstract

See full text

The present invention is directed to systems and methods capable of analyzing a wide variety of input signal waveforms to arbitrate their arrival sequence with a high resolution. In an exemplary embodiment, the apparatus is an arbiter circuit which includes an input means for inputting signals whose waveforms are to be analyzed, a comparator means for distinguishing arrival times of the input signals, the comparator means further including means for quantizing flux, and an output means for outputting information which identifies the arrival of at least one of the input signals. In an alternate embodiment, feedback means are provided for compensating asymmetries in the comparator means.
