Claim 0:
1. A receiver configured to receive a multi-level signal having three or more voltage levels that are different from each other, comprising:
a pre-amplifier circuit configured to generate a plurality of intermediate data signals based on an input data signal that is the multi-level signal and a plurality of reference voltages;
a slicer circuit configured to generate a plurality of decision signals based on the plurality of intermediate data signals and a clock signal; and
a decoder circuit configured to generate output data based on the plurality of decision signals, the output data including two or more bits, and
wherein the pre-amplifier circuit comprises:
a first circuit configured to generate one of the plurality of intermediate data signals based on the input data signal and one of the plurality of reference voltages, the first circuit having a first structure; and
a second circuit configured to generate another one of the plurality of intermediate data signals based on the input data signal and another one of the plurality of reference voltages, the second circuit having a second structure different from the first structure.
