Abstract: An operation method of a receiver, which includes setting a coefficient of an equalizer based on one of a plurality of first codes, setting 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 and the amplifier are driven, determining whether the offset calibration is completed, performing a normal operation of obtaining reception data from an input signal, in response to determining that the offset calibration is completed, and removing the voltage offset based on the offset code, in the normal operation.
