Abstract: 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.

Abstract: An integrated circuit device may include a transmission driver and an equalizer. The transmission driver may be configured to, in response to a transmission control data, transmit an output signal to an outside through a signal line in a transmission operation that outputs the output signal to the outside, and provide termination resistance in a reception operation that receives an input signal from the outside through the signal line. The equalizer may be configured to, in response to an equalizer control data, amplify high-frequency components of the output signal in the transmission operation, and to provide termination resistance in the reception operation.
