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.

Receiver for compensating for voltage offset in real time and operation method thereof

A receiver circuit includes an equalizer configured to generate an equalization signal by equalizing an input data signal transferred through a communication channel based on an equalization coefficient; a clock data recovery circuit configured to generate a data clock signal and an edge clock signal based on the equalization signal, generate a data sample signal including a plurality of data bits by sampling the equalization signal in synchronization with the data clock signal, and generate an edge sample signal including a plurality of edge bits by sampling the equalization signal in synchronization with the edge clock signal; and an equalization control circuit configured to control the equalization coefficient by comparing the plurality of data bits and the plurality of edge bits.
