Abstract: A feed forward equalizer includes a plurality of delay circuits connected to each other in series and configured to delay input signals. A plurality of filters respectively correspond to outputs of the plurality of delay circuits, except for a reference output which is an output of a first delay circuit among the plurality of delay circuits, and the input signals. A calculator configured to sum the reference output and outputs of the plurality of filters. Each of the plurality of filters is configured to receive an output of a delay circuit corresponding thereto, among the plurality of filters, and the reference output.

Abstract: Provided are a transmitting device connected to a receiving device via a channel and the receiving device connected to the transmitting device via a channel. The transmitting device connected to a receiving device includes: a transmitter connected to the channel via an output node and configured to transmit, via the channel, a transmission signal to the receiving device, the transmitter having a transmission impedance associated therewith that is variable; and a monitoring device configured to detect a channel impedance of the channel and a receiving impedance of the receiving device by monitoring a voltage level of the output node, the monitoring device configured to set the transmission impedance based on the channel impedance and the receiving impedance.

Abstract: A system for transceiving data based on a clock transition time is provided. A transmitting device included in the system includes at least one first transmitting circuit configured to transmit data via a wired channel by changing a clock transition time based on the data, wherein the at least one first transmitting circuit includes a skew controller configured to output a skew clock generated by controlling a duty ratio and a skew of an input clock, and a phase-difference modulator configured to output a transmission signal including information about the data generated by changing a transition time of the skew clock based on the data.
