Abstract
A transmitting device includes a calibration circuit and a transmission circuit. The calibration circuit generates calibration codes by performing a calibration operation. The calibration circuit also generates compensation calibration codes by increasing or decreasing values of the calibration codes according to whether a number of codes among the calibration codes having a predetermined level is greater than or equal to a threshold value. The transmission circuit drives a signal transmission line based on an input signal and the compensation calibration codes.
