Abstract
A common-mode voltage controller for adjusting common-mode voltages between a first buffer and a second buffer at a subsequent stage or a preceding stage of the first buffer in a signal transmission circuit, comprising: a first reference voltage generation unit for generating a common-mode voltage corresponding to the first buffer; a second reference voltage generation unit for generating a common-mode voltage corresponding to the second buffer at the subsequent stage or the preceding stage; and a control signal generation unit for generating a control signal for controlling a common-mode voltage of the first buffer according to a difference voltage between an output of the first reference voltage generation unit and an output of the second reference voltage generation unit, and giving the control signal to the first buffer and first reference voltage generation unit.
