Transmitter circuit and operation method thereof

A transmitter circuit, comprising:

• a delay circuit configured to delay input data by a delay value to generate output delay data;
• a delay replica configured to have a same delay characteristic as the delay circuit;
• a first encoder configured to generate a delay compensation signal based on information from the delay replica, the delay circuit being further configured to determine the delay value based on the delay compensation signal;
• and
• a feed-forward equalizer (FFE) 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.

A transmitter circuit, comprising:

• an encoder configured to receive an impedance code that is generated based on impedance calibration for impedance matching and to generate an equalization compensation signal based on the impedance code;
• a delay circuit configured to output delay data that are delayed by a delay value from input data;
• and
• a feed-forward equalizer (FFE) configured to receive the input data and the delay data, to determine an equalization coefficient used for the delay data based on the equalization compensation signal, and to equalize the input data based on a main coefficient used for the input data and the equalization coefficient to generate transmission data.
