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.

Abstract: An electronic circuit includes a clock recovery circuit that generates a first reference clock signal based on first reception data and generates a second reference clock signal based on second reception data received after the first reception, a sampling clock generator that generates a sampling clock signal having a phase based on a phase difference between the first reference clock signal and the second reference clock signal, and a sampler that recovers the second reception data based on the generated sampling clock signal.
