In a transmitter circuit, an impedance calibration circuit is configured to generate an impedance code for impedance matching, an encoder is configured to receive the impedance code and to generate a delay compensation signal based on the impedance code. A delay circuit is configured to output delay data that are delayed from input data by a delay value determined based on the delay compensation signal. A feed-forward equalizer is configured to receive the input data and the delay data, and to equalize the input data based on a main coefficient used for the input data and an equalization coefficient used for the delay data to generate transmission data.
