Abstract
A data transmitter may include a transmitter circuit and a calibration controller. The transmitter circuit is configured to be coupled to a receiver through a channel, and configured to provide an output signal to the channel based on an input signal and adjust an output impedance value according to a bias signal. The calibration controller is configured to adjust the bias signal by comparing the output signal of the transmitter circuit to a reference signal during a calibration operation.
