1. An operation method of a receiver comprising:
setting, as an equalizer coefficient, a coefficient of an equalizer based on one of a plurality of first codes;
setting, as an amplifier coefficient, a coefficient of an amplifier based on one of a plurality of second codes;
performing offset calibration by driving the equalizer and the amplifier based on the coefficient of the equalizer and the coefficient of the amplifier;
storing an offset code corresponding to a voltage offset generated when the equalizer is driven by the equalizer coefficient and the amplifier is driven by amplifier coefficient;
determining whether the offset calibration is completed;
in response to determining that the offset calibration is completed, performing a normal operation of obtaining reception data from an input signal; and
removing the voltage offset based on the offset code, in the normal operation.
