1. An integrated circuit device for receiving a signal transmitted via an electrical signal conductor, the integrated circuit device comprising:

  • a first receiver circuit to sample the signal according to at least two threshold levels to generate data samples;

    a level sampler to sample the signal to generate error samples; and

    an adaptive module to adjust the at least two threshold levels according to the data samples from the first receiver circuit and the error samples from the level sampler;

    the first receiver circuit including;

    a first sampling circuit to sample the signal and generate a first sample value that indicates whether the signal exceeds a first threshold level;

    a second sampling circuit to sample the signal and generate a second sample value that indicates whether the signal exceeds a second threshold level; and

    a first select circuit coupled to receive the first and second sample values from the first and second sampling circuits and configured to select, according to a previously generated sample value, either the first sample value or the second sample value to be output as a selected sample value.
