Abstract
A reference voltage generation device includes a noise information generation circuit configured to generate power noise information based on a first power noise and a second power noise, the first power noise and the second power noise generated based on a first power and a second power supplied to a first electronic device and propagated from the first electronic device to a second electronic device through a communication line, and the first electronic device and the second electronic device configured to perform data communication using a multi-level signaling scheme. The device includes a reference voltage generation circuit configured to generate three or more reference voltages for the multi-level signaling scheme based on the power noise information, and the second electronic device is configured to use the three or more reference voltages.
