1. A receiver circuit for multi-level amplitude signaling, the receiver circuit comprising:

  • a peak detector for detecting a peak voltage of a multi-level amplitude signal which includes at least three amplitude levels for each symbol period;

    a reference voltage generator for generating a plurality of reference voltages at least partially in response to the peak voltage; and

    a comparator circuit which uses the plurality of reference voltages to detect an amplitude level of the multi-level amplitude signal.
